Description Maurits van der Schee 2004-10-31 17:40:31 UTC 
The search doesn't return results when there is more than one match. I changed
the code in line 329-330 of includes/SearchEngine.php from:

$cond .= " (MATCH (##field##) AGAINST ('" .wfStrencode( $word ). "'))";

to:

$cond .= " (##field## REGEXP '[[:<:]]".wfStrencode( $word )."[[:>:]]')";

Now it works as expected. Just wanted to share this. 

Context: Redhat 9 default installation with apache and mysql.

What does "more than one match" mean? What are the actual results? What 
are you testing with? Can you confirm that the search index is correct? Are 
the terms too short for the search index?

If you do this, your search will be *incredibly* slow since it will scan the 
entire database's text, entry by entry, on every search.
Comment 2 Brion Vibber 2004-11-01 09:41:30 UTC 
The sample search term provided via e-mail works fine after addition of a third page to the 
wiki so that term was not automatically discarded as uninformative (present in 50% of the 
search database).
