[I'm not sure whether this is the right place to post this, but I couldn't find a better one]

I wanted to find information in the forum on the "WHERE IN" SQL clause. So I started searching using various combinations of keywords using "in" and "where". All queries returned no results.

But there are threads including the combinations of keywords I was looking at, e.g. a thread called '"IN" operator': http://www.llblgen.com/tinyforum/Messages.aspx?ThreadID=4583

Similar problem arises if you try to search for anything that includes the word "where".

So I'm wondering, am I doing something wrong, or is this a bug in the search implementation of the forum?
