Searching less than 4 ?

Using the search function, it seems that it doesn't work at all !

I was looking for any occurences of the word "OVH", in the yacs articles.
Well, :[ .... it gives nothing at all. Worth, it seems to totally ignore the request and nicely proposes the search panel... again.
I tried again with "IBM", "Doc", "PhP", and obtained the same result.
But, with "PhP4", "IBM.", "Docs", it works ! :o
So, I presume that the search engine doesn't take arguments with less than 4 characters.
Can some one confirm this behavior ? Is it a bug or a feature ?
In that case, it would be nice to be able to search such "little" words like acronymes.
