				+"Random sort" feature
			
 
				+---------------------
			
 
				+This module defines the "Random sort" feature (feature key:
			
 
				+"search_api_random_sort") that allows to randomly sort the results returned by a
			
 
				+search. With a server supporting this, you can use the "Global: Random" sort to

				+sorting will be provided.

				+For developers:
			
 
				+A service class that wants to support this feature has to check for a
			
 
				+"search_api_random" field in the search query's sorts and insert a random sort
			
 
				+in that position. If the query is sorted in this way, then the
			
 
				+"search_api_random_sort" query option can contain additional options for the

				+- seed: A numeric seed value to use for the random sort.

				+"BETWEEN operator" feature
			
 
				+--------------------------
			
 
				+This module defines the "BETWEEN operator" feature (feature key:
			
 
				+"search_api_between") that adds the "BETWEEN" and "NOT BETWEEN" filter
			
 
				+operators to search queries. If your search server supports this feature, you
			
 
				+can use the "Is between" and "Is not between" operators when adding Views
			
 
				+filters for numeric, string or date types.
			
 
				+
			
 
				+For developers:
			
 
				+A service class that wants to support this feature has to accept "BETWEEN" and
			
 
				+"NOT BETWEEN" as additional $operator values in query conditions. The value in

				+Access features
			
 
				+---------------
			
 
				+Search views created with this module contain two query settings (located in
			
 
				+the "Advanced" fieldset) which let you control the access checks executed for
			
 
				+search results displayed in the view.
			
 
				+
			
 
				+- Bypass access checks
			
 
				+This option allows you to deactivate access filters that would otherwise be
			
 
				+added to the search, if the index supports this. This is, for instance, the case
			
 
				+for indexes on the "Node" item type, when the "Node access" data alteration is
			
 
				+activated.
			
 
				+Use this either to slightly speed up searches where additional checks are
			
 
				+unnecessary (e.g., because you already filter on "Node: Published") and there is
			
 
				+no other node access mechanism on your site) or to show certain data that users
			
 
				+normally wouldn't have access to (e.g., a list of all matching node titles,
			
 
				+published or not).
			
 
				+
			
 
				+- Additional access checks on result entities
			
 
				+When this option is activated, all result entities will be passed to an
			
 
				+additional access check, even if search-time access checks are available for
			
 
				+this index. The advantage is that access rules are guaranteed to be enforced –
			
 
				+stale data in the index, which might make other access checks incorrect, won't
			
 
				+influence this access check. You can also use it for item types for which no
			
 
				+other access mechanisms are available.
			
 
				+However, note that results filtered out this way will mess up paging, result
			
 
				+counts and possibly other things too (like facet counts), as the result row is
			
 
				+only hidden from display after the search has been executed. Where possible,
			
 
				+you should therefore only use this in combination with appropriate filter
			
 
				+settings ensuring that only when the index isn't up-to-date items will be
			
 
				+filtered out this way.
			
 
				+This option is only available for indexes on entity types.
			
 
				+
			
 
				+Other features
			
 
				+--------------
			
 
				+- Change parse mode
			
 
				+You can determine how search keys entered by the user will be parsed by going to
			
 
				+"Advanced" > "Query settings" within your View's settings. "Direct" can be
			
 
				+useful, e.g., when you want to give users the full power of Solr. In other
			
 
				+cases, "Multiple terms" is usually what you want / what users expect.
			
 
				+Caution: For letting users use fulltext searches, always use the "Search:
			
 
				+Fulltext search" filter or contextual filter – using a normal filter on a
			
 
				+fulltext field won't parse the search keys, which means multiple words will only
			
 
				+be found when they appear as that exact phrase.
