Search / Autocomplete / Improvements

[fxprunayre]

Display resource type icon.

In catalogues containing various types of records (eg. datasets, series, services, tabular data, applications, models ...) add the type icon indicator to the suggestion list to help user focus on particular type of records.

This can be disabled by removing autocompleteConfig._source. To enabled it, set it to:

  "_source": ['resourceTitle*', 'resourceType'],

Suggestion size

Also add the possibility to set the number of suggestions using autocompleteConfig.size.

Suggestion and sorting

• Scoring, also promote a bit more series by default.
• Add support for multiple sort fields (eg. resourceType and title)

          sortBy: "resourceType,resourceTitleObject.default.keyword",
          sortOrder: "asc,asc"* Record history / UUID filter (was not migrated to Elasticsearch)

Make more consistent record selection in admin console for various settings:

• Settings / Preferred template (sorted by type and then title)
• CSW settings / Record for capability
• Source settings / Record for capability

Before:

After:

• Record history / UUID filter (was not migrated to Elasticsearch)

Misc.

• Add support for "*" to trigger suggestion

• Improve performance of autocomplete query by only retrieving the required fields.
• Search / Fix wrong order when sortOrder was set to ""

For me works in the search UI, but doesn't work in the CSW settings page: http://localhost:8080/geonetwork/srv/eng/admin.console#/settings/csw

Same happens in the Settings page, maybe the directive is not included in the admin bundle?

@fxprunayre, tested with the updated code, it works in the previous pages, but I see a failing request, that without this pull request doesn't occur, so should be related:

http://localhost:8080/geonetwork/srv/api/search/records/_search

{
"servlet":"spring",
"message":"Error is: Bad Request.\nRequest:\n{"query":{"bool":{"must":[{"multi_match":{"fields":["id","uuid"]}},{"terms":{"isTemplate":["y","n","s"]}},{"terms":{"draft":["n","y","e"]}}],"filter":{"query_string":{"query":"*:*"}}}}}\n.\nError:\n{"error":{"root_cause":[{"type":"parsing_exception","reason":"No text specified for multi_match query","line":1,"col":65}],"type":"x_content_parse_exception","reason":"[1:65] [bool] failed to parse field [must]","caused_by":{"type":"parsing_exception","reason":"No text specified for multi_match query","line":1,"col":65}},"status":400}.",

Indeed @josegar74 some issue with null or empty string check. Should be better now.

@fxprunayre no errors now, but in the Sources page I get suggested also the templates, in the CSW page it looks fine.
