[edit] Details
This config var is extremely obsolete and applied only to MediaWiki 1.5 and below running on MySQL 3.x. Nearly everybody today should be looking at Manual:FAQ#…is a search for a short keyword giving no hits? for this issue.
Minimum string length that the search engine will search on.
- The Go function will take you to a page that is an exact match for the name.
- The Search function will appear to search and give no results.
- MySQL 3.x
- Used to discard words that MySQL will not return any results for. Shorter values configure mysql directly.
- MySQL 4.x and later
- Ignore $wgDBminWordLen and configure mySQL directly.
To configure mySQL, see the mySQL fulltext fine-tuning documentation (4.0/4.1, 5.1). The only table with a fulltext index in wikimedia is searchindex, so after changing the mySQL configuration and restarting mySQL, issue the command REPAIR TABLE searchindex QUICK;.
[edit] Note
While the effects of the setting were removed in version 1.6, the variable wasn't removed from DefaultSettings until version 1.14 (r41038).
