Hi,
I've been using the existing Mediawiki search engine and implemented a
docfile search based on the filesearch extension (running the doc thru
antiword). I realize that wikipedia is now lucence, but I have some
suggestions to improve the mysql search.
First off I noticed the maintenance rebuildTextIndexes.php has a bug that it
doesn't index any namespace other than main. It also needs text on the page
so I make the following hack (line 59):
$u = new SearchUpdate( $s->page_id,
Title::makeName($s->page_namespace,$s->page_title), $revtext);
if($u->mNamespace == NS_IMAGE && !$u->mText )
$u->mText = "File"; // Always have some text for images
to force indexing
This allows it to index files with no text, and ensures the namespace.
Also the MySQL ranking is not working at the moment:
$m2 = str_replace(" IN BOOLEAN MODE", "", $match);
$m2 = str_replace("+", "", $m2);
SELECT page_id, page_namespace, page_title, {$m2} as relevance FROM $page,
.$searchindex WHERE page_id=si_masterid AND $match
I've replaced this query with a hacked multiwiki one that shows rank, so I
hope that makes sense!
This tip was from
http://dev.mysql.com/doc/refman/5.0/en/fulltext-search.html , the second
comment
Both might be a nice addition for the core engine, for people without
lucene...
Final fix was to the filesearch extension - it should return true, or
subsequent indexing extensions break extensions.
One last question: when updating the index, should I hook the ondeletepage
to remove an index or should there be another hook somewhere else?
Best regards,
Alex
