Additional Inherited Members
Public Member Functions inherited from SearchEngine
	augmentSearchResults (SearchResultSet $resultSet)
	Augment search results with extra data.
	completionSearch ( $search)
	Perform a completion search.
	completionSearchWithVariants ( $search)
	Perform a completion search with variants.
	defaultPrefixSearch ( $search)
	Simple prefix search for subpages.
	delete ( $id, $title)
	Delete an indexed page Title should be pre-processed.
	extractTitles (SearchSuggestionSet $completionResults)
	Extract titles from completion results.
	getFeatureData ( $feature)
	Way to retrieve custom data set by setFeatureData or by the engine itself.
	getNearMatcher (Config $config)
	Get service class to finding near matches.
	getProfiles ( $profileType, User $user=null)
	Get a list of supported profiles.
	getSearchIndexFields ()
	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.
	searchArchiveTitle ( $term)
	Perform a title search in the article archive.
	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)
	Way to pass custom data for engines.
	setLimitOffset ( $limit, $offset=0)
	Set the maximum number of results to return and how many to skip before returning the first.
	setNamespaces ( $namespaces)
	Set which namespaces the search should include.
	setShowSuggestion ( $showSuggestion)
	Set whether the searcher should try to build a suggestion.
	setSort ( $sort)
	Set the sort direction of the search results.
	supports ( $feature)
	textAlreadyUpdatedForIndex ()
	If an implementation of SearchEngine handles all of its own text processing in getTextFromContent() and doesn't require SearchUpdate::updateText()'s rather silly handling, it should return true here instead.
	transformSearchTerm ( $term)
	Transform search term in cases when parts of the query came as different GET params (when supported), e.g.
	update ( $id, $title, $text)
	Create or update the search index record for the given page.
	updateTitle ( $id, $title)
	Update a search index record's title only.

static	defaultNamespaces ()
	An array of namespaces indexes to be searched by default.
static	getNearMatch ( $searchterm)
	If an exact title match can be found, or a very slightly close match, return the title.
static	getNearMatchResultSet ( $searchterm)
	Do a near match (see SearchEngine::getNearMatch) and wrap it into a SearchResultSet.
static	getSearchTypes ()
	Return the search engines we support.
static	legalSearchChars ( $type=self::CHARS_ALL)
	Get chars legal for search NOTE: usage as static is deprecated and preserved only as BC measure.
static	namespacesAsText ( $namespaces)
	Get a list of namespace names useful for showing in tooltips and preferences.

Dummy class to be used when non-supported Database engine is present.

Todo

FIXME: Dummy class should probably try something at least mildly useful, such as a LIKE search through titles.
