+Full text search dev reference.
+
+1. OVERVIEW
+
+ * All entities are searched through title and description using
+ MySQL's native fulltext search when possible, and LIKE %...% when not.
+ This can be overriden on a type/subtype basis.
+
+ * Entities are displayed in a standard list view consisting of a
+ title, blurb, and icon of the owning entity. This can be overriden
+ on a type/subtype basis.
+
+ * Search is separated based upon types/subtypes pairs and any
+ registered custom search.
+
+ * METADATA, ANNOTATIONS, AND PRIVATE DATA ARE NOT SEARCHED.
+ These are used in a variety of ways by plugin authors and generally
+ should not be displayed. There are exceptions (profile fields and
+ comments) but if a plugin needs to match against metadata,
+ annotations, or private data it must register a search hook itself.
+
+
+2. SEARCH AND YOUR PLUGIN
+
+ * To appear in search you must register your entity type and subtype
+ by saying in your plugin's init function:
+
+ register_entity_type($type, $subtype);
+
+ If you are extending ElggObject with your own class, it is also advised
+ to add a subtype in your plugin's run_once function by saying:
+
+ add_subtype($type, $subtype, $class);
+
+ * If your plugin uses ElggEntity's standard title and description,
+ and you don't need a custom display, there is nothing else you need
+ to do for your results to appear in search. If you would like more
+ granular control of search, continue below.
+
+
+3.1 CONTROLLING SEARCH -- ENTITIES
+
+ * You can override the default search by responding to the search/type
+ or search/type:subtype hook. Generally, you will be replying to
+ search/object:subtype.
+
+ * Search will first trigger a hook for search/type:subtype. If no
+ results are returned (but not FALSE, see below) a hook for search/type
+ will be triggered.
+
+ * FALSE returned for any search hook will halt results for that type/subtype.
+
+ * Register plugin hooks like this:
+
+ register_plugin_hook('search', 'object:my_subtype', 'my_subtype_search_hook');
+
+ * The hooked function is provided with details about the search query in $param.
+ These include:
+ query
+ offset
+ limit
+ search_type
+ type - Entity type. (Not applicable for custom searches)
+ subtype - Entity subtype. (Not applicable for custom searches)
+ owner_guid
+ friends - Should only entities by friends of the logged in
+ user be searched? (@todo)
+ pagination - Show pagination?
+
+ * The hooked function should respond to search triggers with the
+ following:
+ array(
+ 'count' => A count of ALL entities found,
+ 'entities' => An array of entities.
+ )
+
+ This information is passed directly to the search view, so if you are
+ registering your own custom hook, you can provide more
+ information to display in your custom view.
+
+ * For each entity in the returned array, search expects two pieces of
+ volatile data: search_matched_title and search_matched_description.
+ Set these by saying:
+
+ $entity->setVolatileData('data_name', 'data_value');
+
+ Again, if you are customizing your search views, you can add anything
+ you need.
+
+
+3.2 CONTROLLING SEARCH - ENTITY VIEWS
+
+ * The default view for entities is search/entity.
+
+ * Search views are separate from the object/entity views because
+ view types might not match entity types.
+
+ * The default search listing view interates through each entity
+ found and passes to the entity view. See 3.3 for more information
+ about listing views.
+
+ * Views are discovered in the following order. The first search view
+ found is used.
+ search/type/subtype/entity (For entity-based searches only)
+ search/type/entity
+ search/entity
+
+ * The following parameters are passed in $vars to the entity view by
+ the default listing view:
+ entity => The current returned entity
+ params =>
+ results
+
+ * Example: To create an entity view for an ElggObject of subtype blog,
+ create a file called:
+ views/default/search/object/blog/entity.php
+
+ To create an entity view for a custom search mysearch, create a file
+ called:
+ views/default/search/mysearch/entity.php
+
+
+3.3 CONTROLLING SEARCH - LISTING VIEWS
+
+ * The default search view is search/listing.
+
+ * For each entity in the returned array, search expects two pieces of
+ volatile data: search_matched_title and search_matched_description.
+
+ * Views are discovered in the following order. The first search view
+ found is used.
+ search/type/subtype/listing (For entity-based searches only)
+ search/type/listing
+ search/listing
+
+ * The view is called with the following in $vars:
+ results => The results from the search/type:subtype hook
+ params => The params passed to the search/type:subtype hook
+
+ * Example: To create a listing view for ElggObjects with the subtype
+ of blog, create a file called:
+ views/default/search/object/blog/listing.php
+
+ To create a listing view for the custom search mysearch, create a file
+ called:
+ views/default/search/mysearch/listing.php
+
+
+3.4 CONTROLLING SEARCH - CUSTOM SEARCH
+
+ * Non-entities, including information from 3rd party applications,
+ can easily be included in search by registering a custom search hook
+ that responds to the search_types/get_types trigger:
+
+ register_plugin_hook('search_types', 'get_types', 'my_custom_search_hook_function');
+
+ In this function, append to the array sent in $value with the name of
+ your custom search:
+
+ function my_custom_search_hook_function($hook, $type, $value, $params) {
+ $value[] = 'my_custom_search';
+ return $value;
+ }
+
+ Search will trigger a hook for search/my_custom_search, which your
+ plugin should respond to as detailed in section 3.1 above.
+
+
+4. HINTS
+
+ * Use search_get_relevant_substring() to extract and highlight
+ relevant substrings for the search_match_title and description.
+
+ * If searching in 3rd party applications, create a temporary
+ ElggObject to hold the results. No need to save it since search
+ uses volatile data.
+ $entity = new ElggObject();
+ $entity->owner_guid = use_magic_to_match_to_a_real_user();
+ $entity->setVolatileData('search_matched_title', '3rd Party Integration');
+ $entity->setVolatileData('search_matched_description', 'Searching is fun!');
+
+ return array(
+ 'count' => $count,
+ 'entities' => array($entity)
+ ); \ No newline at end of file
