 Get fields for search index.
 
 getSort ()
 Get the sort direction of the search results.
 
 getTextFromContent (Title $t, Content $c=null)
 Get the raw text for updating the index from a content object Nicer search backends could possibly do something cooler than just returning raw text.
 
 getValidSorts ()
 Get the valid sort directions.
 
 makeSearchFieldMapping ( $name, $type)
 Create a search field definition.
 
 normalizeText ( $string)
 When overridden in derived class, performs database-specific conversions on text to be used for searching or updating search index.
 
 replacePrefixes ( $query)
 Parse some common prefixes: all (search everything) or namespace names and set the list of namespaces of this class accordingly.
 
 searchText ( $term)
 Perform a full text search query and return a result set.
 
 searchTitle ( $term)
 Perform a title-only search query and return a result set.
 
 setFeatureData ( $feature, $data)
