This should be fixed in the future.

Member Function Documentation

◆ getDataForSearchIndex()

FileContentHandler::getDataForSearchIndex ( WikiPage  $page,
ParserOutput  $output,
SearchEngine  $engine 
)

Return fields to be indexed by search engine as representation of this document.

Overriding class should call parent function or take care of calling the SearchDataForIndex hook.

The $output must be the result of a call to getParserOutputForIndexing() on the same content handler. That method may return ParserOutput without HTML; this base implementation does not rely on the HTML being present, so it is safe to call even by subclasses that override getParserOutputForIndexing() to skip HTML generation. On the other hand, since the default implementation of getParserOutputForIndexing() does generate HTML, subclasses are free to rely on the HTML here if they do not override getParserOutputForIndexing().

Stability: stable
to override
Parameters
WikiPage$pagePage to index
ParserOutput$output
SearchEngine$engineSearch engine for which we are indexing
Returns
array Map of name=>value for fields
Since
1.28

Reimplemented from WikitextContentHandler.

Definition at line 36 of file FileContentHandler.php.

References $file, $title, WikiPage\getTitle(), and NS_FILE.

◆ getFieldsForSearchIndex()

FileContentHandler::getFieldsForSearchIndex ( SearchEngine  $engine)

Get fields definition for search index.

Todo:
Expose title, redirect, namespace, text, source_text, text_bytes field mappings here. (see T142670 and T143409)
Stability: stable
to override
Parameters
SearchEngine$engine
Returns
SearchIndexField[] List of fields this content handler can provide.
