I would like to make a suggestion about the Zimbra Wiki. (Not the 'documents' section of a ZCS installation, but wiki.zimbra.com itself.)

As is the default with MediaWiki installations, it is currently not possible to search for words with less than 4 characters in them. This makes sense for something the scale of Wikipedia, but not necessarily the Zimbra Wiki where it is likely that readers might want to search for words like mta, hsm, pop, cos, etc(!).

The fix is to do this in my.cnf for the MySQL installation that serves the MediaWiki content:

By the way, the general search box (at the top of most zimbra.com pages) does return results for 3 letter words; so it might be nice to change the wiki specific search for consistency.
