Search Configuration Guide

This page describes how you can configure the search configuration.

{
    "search": [
        {
            "name": "Application default search", 
            "default": true,
            "filteredWithContaints": true,
            "filterQueries": [
                { "query": "+TYPE:'cm:folder' OR +TYPE:'cm:content'" }
            ]
        }, 
        {
            "name": "Application secondary search",
            "default": false,
            "filteredWithContaints": true,
            "filterQueries": [
              { "query": "+TYPE:'cm:folder' OR +TYPE:'cm:content'" }
              { "query": "-TYPE:'st:site' AND -ASPECT:'st:siteContainer' AND -ASPECT:'sys:hidden'" }
            ]
        }
    ]
}

You can have arrayed config. At any point in the application only one of this configuration will be used for search.

The one with default considered as default configuration and user should be able to switch to other configuration.

Supported Layouts

ADF support two kinds of search layouts.

Expansion card based layouts
Chip based layout

The layout is generated for the default/selected search configuration.

Steps involved in search configuration

In the three steps you can specify the search configuration. i.e

1. Identify the search use case
2. find/construct search query
3. Add it in the adf search configuration section

You may find it useful to check out the following resources for background information before customizing the search UI:

Configuration

You can configure the component using the search entry in the app.config.json file. A typical configuration is shown below:

{
    "search": {
        "name": "Application search",
        "default": true,
        "filterWithContains": true,
        "sorting": {
            "options": [
                { 
                    "key": "name",
                    "label": "Name",
                    "type": "FIELD",
                    "field": "cm:name",
                    "ascending": true 
                },
            ],
            "defaults": [
                {
                    "key": "name",
                    "type": "FIELD",
                    "field": "cm:name",
                    "ascending": true 
                }
            ]
        },
        "filterQueries": [
            { "query": "+TYPE:'cm:folder' OR +TYPE:'cm:content'" },
            { "query": "-cm:creator:System" }
        ],
        "facetQueries": {
            "mincount": 1,
            "label": "My facet queries",
            "pageSize": 4,
            "expanded": true,
            "queries": [
                { "query": "content.mimetype:text/html", "label": "Type: HTML" },
                { "query": "content.size:[0 TO 10240]", "label": "Size: xtra small" },
                { "query": "content.size:[10240 TO 102400]", "label": "Size: small" },
                { "query": "content.size:[102400 TO 1048576]", "label": "Size: medium" },
                { "query": "content.size:[1048576 TO 16777216]", "label": "Size: large"},
                { "query": "content.size:[16777216 TO 134217728]", "label": "Size: xtra large" },
                { "query": "content.size:[134217728 TO MAX]", "label": "Size: XX large" }
            ],
            "settings": {
              "allowUpdateOnChange": false,
              "hideDefaultAction": true
            }
        },
        "facetFields": {
            "expanded": true,
            "fields": [
                { 
                    "field": "content.mimetype",
                    "mincount": 1,
                    "label": "Type",
                    "settings": {
                        "allowUpdateOnChange": false,
                        "hideDefaultAction": true,
                        "facetOrder": 100
                    }
                },
                { 
                    "field": "creator",
                    "mincount": 1,
                    "label": "Creator",
                    "settings": {
                        "allowUpdateOnChange": false,
                        "hideDefaultAction": true,
                        "facetOrder": 200
                    }
                },
            ]
        },
        "categories": [
            {
                "id": "queryName",
                "name": "Name",
                "enabled": true,
                "component": {
                    "selector": "text",
                    "settings": {
                        "allowUpdateOnChange": false,
                        "hideDefaultAction": true,
                        "pattern": "cm:name:'(.*?)'",
                        "field": "cm:name",
                        "placeholder": "Enter the name"
                    }
                }
            }
        ]
    }
}

The schema.json file for the app config has further details about available settings, values and formats for the configuration options.

Extra fields and filter queries

You can explicitly define the include section for the query from within the application configuration file. This array is a list of extra data fields to be added to the search results:

{
    "search": {
        ...
        "include": ["path", "allowableOperations"]
        ...
    }
}

You can choose to filter facet field results using 'contains' instead of 'starts with', by using the filterWithContains boolean (default is false):

{
    "search": {
        ...
        "filterWithContains": true
        ...
    }
}

You can choose to display a reset button by setting the 'resetButton' value to true. This 'clean up' button would make it easier for the final user to remove all bucket selections and all search filtering.

{
    "search": {
        ...
        "resetButton": true
        ...
    }
}

You can also provide a set of queries that are always executed alongside the user-defined settings:

{
    "search": {
        ...
        "filterQueries": [
            { "query": "+TYPE:'cm:folder' OR +TYPE:'cm:content'" },
            { "query": "-cm:creator:System" }
        ]
        ...
    }
}

Note that the entries of the filterQueries array are joined using the AND operator.

Sorting

The Sorting configuration section consists of two blocks:

options: a list of items that users can select from
defaults: predefined sorting to use by default

{
    "search": {
        "sorting": {
            "options": [
                { "key": "name", "label": "Name", "type": "FIELD", "field": "cm:name", "ascending": true },
                { "key": "content.sizeInBytes", "label": "Size", "type": "FIELD", "field": "content.size", "ascending": true },
                { "key": "description", "label": "Description", "type": "FIELD", "field": "cm:description", "ascending": true }
            ],
            "defaults": [
                { "key": "name", "type": "FIELD", "field": "cm:name", "ascending": true }
            ]
        }
    }
}

The properties of the options objects are as follows:

Name	Type	Description
key	string	Unique key to identify the entry. This can also be used to map `DataColumn` instances.
label	string	Display text, which can also be an i18n resource key.
type	string	This specifies how to order the results. It can be based on a field, based on the position of the document in the index, or by score/relevance.
field	string	The name of the field.
ascending	boolean	The sorting order defined as `true` for ascending order and `false` for descending order

See the information on sorting in the Search API for further details.

Categories and widgets

The Search Settings component and Query Builder require a categories section in the configuration.

Categories are used to configure the UI widgets that let the user edit the search query at runtime. Every category is represented by a single Angular component, which can be either a simple one or a composite one.

export interface SearchCategory {
    id: string;
    name: string;
    enabled: boolean;
    expanded: boolean;
    component: {
        selector: string;
        settings: SearchWidgetSettings;
    };
    rules?: {
        visible: string;
    };
}

The interface above also describes entries in the search.query.categories section for the app.config.json file.

Note: you must provide at least one category field in order to execute the query, so that filters and selected facets are applied.

The Search Filter supports a number of components out of the box, each implementing an ADF search widget interface. The selector property specifies which widget is used for a category:

Widget name	Selector	Description
Check List	`check-list`	Toggles individual query fragments for the search
Date Range	`date-range`	Allows for selecting date range for a field containing dates
Date Time Range	`datetime-range`	Allows for selecting date and time rande for a field containing dates
Number Range	`number-range`	Specifies a range of numeric values that a field may contain
Radio List	`radio`	Selects one query fragment from a list of options
Search Filter Autocomplete	`autocomplete-chips`	Provides an input with autocomplete options representing conditions to form search query
Search Logical Filter	`logical-filter`	Provides 4 inputs representing logical conditions to form search query from
Slider	`slider`	Selects a single numeric value in a given range that a field may contain
Text	`text`	Specifies a text value that a field may contain

You can also implement your own custom search widgets. See the Search Widget Interface page for full details of how to do this.

Widget settings

Each type of widget has its own settings. For example Number editors may parse minimum and maximum values, while Text editors can support value formats or length constraints.

You can use component.settings to pass any information to a widget using the SearchWidgetSettings interface:

export interface SearchWidgetSettings {
    field: string;
    /* allow the user to update search in every change */
    allowUpdateOnChange?: boolean;
    /* allow the user hide default search actions. So widget can have custom actions */
    hideDefaultAction?: boolean;
    /* describes the unit of the value i.e byte for better display message */
    unit?: string;
    /* describes query format */
    format?: string;
    /* allow the user to search only within predefined options */
    allowOnlyPredefinedValues?: boolean;
    /* allow the user to predefine autocomplete options */
    autocompleteOptions?: AutocompleteOption[];

    [indexer: string]: any;
}

Facet Fields

{
    "search": {
        "facetFields": {
            "expanded": true,
            "fields": [
                { 
                    "field": "content.mimetype",
                    "mincount": 1,
                    "label": "Type",
                    "settings": {
                        "allowUpdateOnChange": false,
                        "hideDefaultAction": true,
                        "facetOrder": 100
                    }
                },
                { 
                    "field": "creator",
                    "mincount": 1,
                    "label": "Creator",
                    "settings": {
                        "allowUpdateOnChange": false,
                        "hideDefaultAction": true,
                        "facetOrder": 200
                    }
                },
            ]
        }
    }
}

Every field declared within the facetFields group is presented by a separate collapsible category at runtime.

By default, users see only the top 5 entries. If there are more than 5 entries, a button to show more items is displayed to let the user move to the next block of results.

Note: Facet Fields setting can be controlled by passing settings as part the config.

FacetField Properties

Name	Type	Default	Description
field	string		Specifies the facet field.
mincount	number	1	Specifies the minimum count required for a facet field to be included in the response. The default value is 1.
label	string		Specifies the label to include in place of the facet field.
prefix	string		Restricts the possible constraints to only indexed values with a specified prefix.
limit	number		Maximum number of results
pageSize	number	5	Display page size
offset	number		Offset position
settings	FacetFieldSettings		Settings allowing for controlling fields behavior and order

FacetFieldSetting

Name	Type	Default	Description
allowUpdateOnChange	`boolean`	false	Specifies whether search should be executed automatically after FacetField value changes.
hideDefaultAction	`boolean`	true	Specifies whether default field actions should be visible.
facetOrder	`number`		Specifies the order of facets. Lower numbers are displayed first.
bucketSortBy	`string`		Specifies sort criteria of facet queries. Possible values are "LABEL" and "COUNT".
bucketSortDirection	`string`		Specifies sort order of facet queries. Possible values are "ASCENDING" and "DESCENDING".

Facet Queries

These provide custom categories based on admin-defined facet queries.

{
    "search": {
        "facetQueries": {
            "mincount": 1,
            "label": "My facet queries",
            "pageSize": 4,
            "expanded": true,
            "queries": [
                { "query": "content.mimetype:text/html", "label": "Type: HTML" },
                { "query": "content.size:[0 TO 10240]", "label": "Size: xtra small" },
                { "query": "content.size:[10240 TO 102400]", "label": "Size: small" },
                { "query": "content.size:[102400 TO 1048576]", "label": "Size: medium" },
                { "query": "content.size:[1048576 TO 16777216]", "label": "Size: large"},
                { "query": "content.size:[16777216 TO 134217728]", "label": "Size: xtra large" },
                { "query": "content.size:[134217728 TO MAX]", "label": "Size: XX large" }
            ],
            "settings": {
              "allowUpdateOnChange": false,
              "hideDefaultAction": true
            }
        }
    }
}

By default, the queries declared in the facetQueries are collected into a single collapsible category. The mincount property allows setting the minimum count required for a facet field to be displayed. By default, only the queries that have 1 or more response entries are displayed at runtime. The component provides a Show more button to display more items if the number of items exceeds the pageSize value.

You can provide a custom label (or i18n resource key) for the default resulting collapsible category. If you need to display more resulting collapsible categories, you can group different facet queries under custom labels by using the group property on those facet queries:

{
    "search": {
        "facetQueries": {
            "label": "Facet queries",
            "pageSize": 5,
            "expanded": true,
            "mincount": 0,
            "queries": [
                { "query": "content.mimetype:text/html", "label": "Type: HTML", "group": "Type facet queries" },
                { "query": "content.size:[0 TO 10240]", "label": "Size: xtra small", "group": "Size facet queries"},
                { "query": "content.size:[10240 TO 102400]", "label": "Size: small", "group": "Size facet queries"},
                { "query": "content.size:[102400 TO 1048576]", "label": "Size: medium", "group": "Size facet queries" },
                { "query": "content.size:[1048576 TO 16777216]", "label": "Size: large", "group": "Size facet queries" },
                { "query": "content.size:[16777216 TO 134217728]", "label": "Size: xtra large", "group": "Size facet queries" },
                { "query": "content.size:[134217728 TO MAX]", "label": "Size: XX large", "group": "Size facet queries" }
            ],
            "settings": {
              "allowUpdateOnChange": false,
              "hideDefaultAction": true
            }
        }
    }
}

Note: settings property used to control UI actions and interaction. i.e

{
    "search": {
        "facetQueries": {
            "label": "Facet queries",
            "pageSize": 5,
            "expanded": true,
            "mincount": 0,
            "queries": [
                { "query": "+created:2018", "label": "Created This Year" },
                { "query": "+modifier:admin", "label": "Admin modifier" }
            ],
            "settings" : {
                "allowUpdateOnChange": false,
                "hideDefaultAction": true,
                "facetOrder": 100,
                "bucketSortBy": "LABEL",
                "bucketSortDirection": "ASCENDING"
            }
        }
    }
}

This will result in the following display of the grouped facet queries:

The pageSize property allows you to define the number of results to display. Users will see Show more or Show less buttons as appropriate for the result set. The default page size of 5 will be used if you set the value to 0 or omit it entirely.

FacetQueriesSettings

Name	Type	Default	Description
allowUpdateOnChange	`boolean`	false	Specifies whether search should be executed automatically after FacetField value changes.
hideDefaultAction	`boolean`	true	Specifies whether default field actions should be visible.
facetOrder	`number`		Specifies the order of facets. Lower numbers are displayed first.
bucketSortBy	`string`		Specifies sort criteria of facet queries. Possible values are "LABEL" and "COUNT".
bucketSortDirection	`string`		Specifies sort order of facet queries. Possible values are "ASCENDING" and "DESCENDING".

Facet Intervals

These provide custom categories based on admin defined ranges inside intervals. You can specify exactly what you want for each interval in the config file and you can use overlapping ranges if necessary.

FacetIntervals Properties

Name	Type	Description
intervals	array	Specifies the fields to facet by interval.
expanded	boolean	Toggles expanded state of the facet intervals.

Note: Interval fields setting can be controlled by passing settings. Note: the sets parameter from the Search API (which sets the intervals for all fields) is not yet supported.

{
    "search": {
      "facetIntervals":{
        "expanded": true,
        "intervals":[
          {
            "label":"TheCreated",
            "field":"cm:created",
            "sets":[
              { "label":"lastYear", "start":"2017", "end":"2018", "endInclusive":false },
              { "label":"currentYear", "start":"NOW/YEAR", "end":"NOW/YEAR+1YEAR" },
              { "label":"earlier", "start":"*", "end":"2017", "endInclusive":false }
            ]
          },
          {
            "label":"TheModified",
            "field":"cm:modified",
            "sets":[
              { "label":"2016", "start":"2017", "end":"2018", "endInclusive":false },
              { "label":"currentYear", "start":"NOW/YEAR", "end":"NOW/YEAR+1YEAR" },
              { "label":"earlierThan2017", "start":"*", "end":"2017", "endInclusive":false }
            ]
          }
        ]
      }
  }
}

You can specify a value for the mincount property inside each intervals item to set the minimum count required for a facet interval to be displayed. By default, only the intervals that have 1 or more response entries are displayed at runtime. Check the schema.json file for further details about the structure and properties of intervals that you can set inside the configuration file.

Each defined intervals item is collected into its own collapsible category identified uniquely by its label. The code snippet just above will result in the following display of facet intervals:

Highlight

You can configure highlighting using the search entry in the app.config.json file. An example query for search highlighting could look like this:

{
    "search": {
      "highlight": {
        "prefix": "¿",
        "postfix": "?",
        "mergeContiguous": true,
        "fields": [
          {
            "field": "cm:title"
          },
          {
            "field": "description",
            "prefix": "(",
            "postfix": ")"
          }
    
        ]
      }
  }
}

The example above changes the highlighting prefix and postfix from the default to '¿?' for all fields except the "description" field, which uses '()' instead. The highlight information will then be added in each node entry response. An example partial response is shown below:

"entry": {
    "createdAt": "2016-10-12T15:24:31.202+0000",
    "isFolder": true,
    "search": {
        "score": 1,
        "highlight": [
        {
            "field": "cm:title",
            "snippets": [
                "Customized (Workflow) Process Definitions"
            ]
        },
        {
            "field": "description",
            "snippets": [
                "Customized (Workflow) Process Definitions"
            ]
        }
        ]
    },
}
