wfGetDB( $db, $groups=[], $wiki=false)
Get a Database object.
Base search engine base class for database-backed searches.
filter( $text)
Return a 'cleaned up' search string.
Search engine hook base class for Oracle (ConText).
queryNamespaces()
Return a partial WHERE clause to limit the search to the given namespaces.
getIndexField( $fulltext)
Picks which field to index on, depending on what type of query.
update( $id, $title, $text)
Create or update the search index record for the given page.
queryLimit( $sql)
Return a LIMIT clause to limit results on the query.
updateTitle( $id, $title)
Update a search index record's title only.
queryMain( $filteredTerm, $fulltext)
Get the base part of the search query.
searchTitle( $term)
Perform a title-only search query and return a result set.
queryRanking( $filteredTerm, $fulltext)
Does not do anything for generic search engine subclasses may define this though.
static legalSearchChars( $type=self::CHARS_ALL)
Get chars legal for search NOTE: usage as static is deprecated and preserved only as BC measure.
searchText( $term)
Perform a full text search query and return a result set.
parseQuery( $filteredText, $fulltext)
Parse a user input search string, and return an SQL fragment to be used as part of a WHERE clause.
getQuery( $filteredTerm, $fulltext)
Construct the full SQL query to do the search.
This class is used for different SQL-based search engines shipped with MediaWiki.
this class mediates it Skin Encapsulates a look and feel for the wiki All of the functions that render HTML and make choices about how to render it are here and are called from various other places when and is meant to be subclassed with other skins that may override some of its functions The User object contains a reference to a and so rather than having a global skin object we just rely on the global User and get the skin with $wgUser and also has some character encoding functions and other locale stuff The current user interface language is instantiated as and the local content language as $wgContLang
when a variable name is used in a it is silently declared as a new local masking the global

injection txt This is an overview of how MediaWiki makes use of dependency injection The design described here grew from the discussion of RFC T384 The term dependency this means that anything an object needs to operate should be injected from the the object itself should only know narrow no concrete implementation of the logic it relies on The requirement to inject everything typically results in an architecture that based on two main types of and essentially stateless service objects that use other service objects to operate on the value objects As of the beginning MediaWiki is only starting to use the DI approach Much of the code still relies on global state or direct resulting in a highly cyclical dependency which acts as the top level factory for services in MediaWiki which can be used to gain access to default instances of various services MediaWikiServices however also allows new services to be defined and default services to be redefined Services are defined or redefined by providing a callback the instantiator that will return a new instance of the service When it will create an instance of MediaWikiServices and populate it with the services defined in the files listed by thereby bootstrapping the DI framework Per $wgServiceWiringFiles lists includes ServiceWiring php
