FS#2224 Don't allow search on 1 or 2 letter words
other
2011-04-17YoBoY
Searching a wiki can be stressfull for the servers. Actually we can make searches with 1+ letter words.
Try it, the results are useless, and the time response is big. And if you add a wildcard it's worse.
So it should be a good idea to limit the searches and don't allow search on 1 or 2 letter words (or more restrictive?). We can also put a configurable limit like in forums.

Your idea is to allow only search with words with size greater than what? 3?

I would prefer a config option where the administrator can set the minimum length of the searchstring.

3 is a good start, but a configurable minimum lenght is better I think like lupo49 wrote and let people limit or not the searches.

Shouldn't that limit be the same as the limit in the indexer? There is a constant IDX_MINWORDLENGTH which is per default 2 and used for non-numeric tokens. For shorter words the index doesn't contain any information anyway and thus the search only returns matches from the pagename/title search. I don't know why searching for shorter words should take longer than searching for other, very frequent long words. Thus I would say if you are concerned about shorter words setting IDX_MINWORDLENGTH would be the best option (e.g. using inc/preload.php) - and then there should be some error message that searching for words shorter than that limit doesn't work.
