Hi,

Please change the test for "MediaWiki:Nonefound" in the default installation from:

'''Note''': unsuccessful searches are often caused by searching for common words like "have" and "from", which are not indexed, or by specifying more than one search term (only pages containing all of the search terms will appear in the result).

to:

'''Note''': unsuccessful searches are often caused by searching for words shorter then 4 characters, or common words like "have" and "from", which are not indexed, or by specifying more than one search term (only pages containing all of the search terms will appear in the result).

I just spend quite some time figuring out why a search on "IP" did not match a page, while I was sure I had a page on "IP Address ranges".

Obviously, this is a MySQL-specific problem (which only indexes words of 4 chars and up [1]), but I have the impression I'm not the only one who encountered this "feature" of MySQL.

Alternatively, it is very well possible to make a workaround, and recognize the fact that search with a short word is performed by MySQL, but I dislike such a feature, so I propose a generic warning instead, and just hope that MySQL makes it easier to change the min-word-length on a per-table (or per-column or per-database) rather then a per-server basis.

PS: I put the misleading "(in caps)" in the subject because I suspected this was a case-related bug (somehow all my short words were all caps ;-) ); perhaps people will earlier spot this mail when they Google for this quirck.
