/* EXPLAINING THE FACETVIEW OPTIONS
Facetview options can be set on instantiation. The list below details which options are available.
Options can also be set and retrieved externally via $.fn.facetview.options.
Query values can also be read from the query parameters of the current page, or provided in
the "source" option for initial search.
Also, whilst facetview is executing a query, it will "show" any element with the "notify-loading" class.
So that class can be applied to any element on a page that can be used to signify loading is taking place.
Once facetview has executed a query, the querystring used is available under "options.querystring".
And the result object as retrieved directly from the index is available under "options.rawdata".
searchbox_class
---------------
This should only be set if embedded_search is set to false, and if an alternative search box on the page should
be used as the source of search terms. If so, this should be set to
the class name (including preceding .) of the text input that should be used as the source of the search terms.
It is only a class instead of an ID so that it can be applied to fields that may already have an ID -
it should really identify a unique box on the page for entering search terms for this instance of facetview.
So an ID could actually also be used - just precede with # instead of .
This makes it possible to embed a search box anywhere on a page and have it be used as the source of simple
search parameters for the facetview. Only the last text box with this clas will be used.
embedded_search
---------------
Default to true, in which case full search term functionality is created and displayed on the page.
If this is false, the search term text box and options will be hidden, so that new search terms cannot
be provided by the user.
It is possible to set an alternative search term input box on the page instead, by setting this to false and
also setting a searchbox_class value to identify the basic source of search terms, in which case such a box
must be manually created elsewhere on the page.
searchbox_shade
---------------
The background colour to apply to the search box
sharesave_link
--------------
Default to true, in which case the searchbox - if drawn by facetview - will be appended with a button that
shows the full current search parameters as a URL.
config_file
-----------
Specify as a URL from which to pull a JSON config file specifying these options.
facets
------
A list of facet objects which should be created as filter options on the page.
As per elasticsearch facets settings, plus "display" as a display name for the facet, instead of field name.
If these should be nested, define them with full scope e.g. nestedobj.nestedfield.
extra_facets
------------
An object of named extra facet objects that should be submitted and executed on each query.
These will NOT be used to generate filters on the page, but the result object can be queried
for their content for other purposes.
searchbox_fieldselect
---------------------
A list of objects specifying fields to which search terms should be restricted.
Each object should have a "display" value for displaying as the name of the option,
and a "field" option specifying the field to restrict the search to.
search_sortby
----------------
A list of objects describing sort option dropdowns.
Each object requires a "display" value, and "field" value upon which to sort results.
NOTE sort fields must be unique on the ES index, NOT lists. Otherwise it will fail silently. Choose wisely.
enable_rangeselect
------------------
RANGES NEED SOME WORK AFTER RECENT UPDATE, KEEP DISABLED FOR NOW
Enable or disable the ability to select a range of filter values
include_facets_in_querystring
-----------------------------
Default to false.
Whether or not to include full facet settings in the querystring when it is requested for display.
This makes it easier to get the querystring for other purposes, but does not change the query that is
sent to the index.
result_display
--------------
A display template for search results. It is a list of lists.
Each list specifies a line. Within each list, specify the contents of the line using objects to describe
them. Each content piece should pertain to a particular "field" of the result set, and should specify what
to show "pre" and "post" the given field
display_images
--------------
Default to true, in which case any image found in a given result object will be displayed to the left
in the result object output.
description
-----------
Just an option to provide a human-friendly description of the functionality of the instantiated facetview.
Like "search my shop". Will be displayed on the page.
search_url
----------
The URL at the index to which searches should be submitted in order to retrieve JSON results.
datatype
--------
The datatype that should be used when submitting a search to the index - e.g. JSON for local, JSONP for remote.
initialsearch
-------------
Default to true, in which case a search-all will be submitted to the index on page load.
Set to false to wait for user input before issuing the first search.
fields
------
A list of which fields the index should return in result objects (by default elasticsearch returns them all).
partial_fields
--------------
A definition of which fields to return, as per elasticsearch docs http://www.elasticsearch.org/guide/reference/api/search/fields.html
nested
------
A list of keys for which the content should be considered nested for query and facet purposes.
NOTE this requires that such keys be referenced with their full scope e.g. nestedobj.nestedfield.
Only works on top-level keys so far.
default_url_params
------------------
Any query parameters that the index search URL needs by default.
freetext_submit_delay
---------------------
When search terms are typed in the search box, they are automatically submitted to the index.
This field specifies in milliseconds how long to wait before sending another query - e.g. waiting
for the user to finish typing a word.
q
-
Specify a query value to start with when the page is loaded. Will be submitted as the initial search value
if initialsearch is enabled. Will also be set as the value of the searchbox on page load.
predefined_filters
------------------
Facet / query values to apply to all searches. Give each one a reference key, then in each object define it
as per an elasticsearch query for appending to the bool must.
If these filters should be applied at the nested level, then prefix the name with the relevant nesting prefix.
e.g. if the nested object is called stats, call the filter stats.MYFILTER.
filter
-------
JSON document describing an `elasticsearch filter <http://www.elasticsearch.org/guide/reference/api/search/filter/>`_
paging
------
An object defining the paging settings:
from
----
Which result number to start displaying results from
size
----
How many results to get and display per "page" of results
pager_on_top
------------
Default to false, in which case the pager - e.g. result count and prev / next page buttons - only appear
at the bottom of the search results.
Set to true to show the pager at the top of the search results as well.
pager_slider
------------
If this is set to true, then the paging options will be a left and right arrow at the bottom, with the
count in between, but a bit bigger and more slider-y than the standard one. Works well for displaying
featured content, for example.
sort
----
A list of objects defining how to sort the results, as per elasticsearch sorting.
searchwrap_start
searchwrap_end
----------------
HTML values in which to wrap the full result set, to style them into the page they are being injected into.
resultwrap_start
resultwrap_end
----------------
HTML values in which to wrap each result object
result_box_colours
------------------
A list of background colours that will be randomly assigned to each result object that has the "result_box"
class. To use this, specify the colours in this list and ensure that the "result_display" option uses the
"result_box" class to wrap the result objects.
fadein
------
Define a fade-in delay in milliseconds so that whenever a new list of results is displays, it uses the fade-in effect.
post_search_callback
--------------------
This can define or reference a function that will be executed any time new search results are retrieved and presented on the page.
pushstate
---------
Updates the URL string with the current query when the user changes the search terms
linkify
-------
Makes any URLs in the result contents into clickable links
default_operator
----------------
Sets the default operator in text search strings - elasticsearch uses OR by default, but can also be AND
default_freetext_fuzzify
------------------------
If this exists and is not false, it should be either * or ~. If it is * then * will be prepended and appended
to each string in the freetext search term, and if it is ~ then ~ will be appended to each string in the freetext
search term. If * or ~ or : are already in the freetext search term, it will be assumed the user is already trying
to do a complex search term so no action will be taken. NOTE these changes are not replicated into the freetext
search box - the end user will not know they are happening.
