Search Function Problem

[One on One]

Sometimes when I go to search I put in a term that I know most have come up in threads before and I get nothing. I went to Search and left everything on default and put in the word "often" and it said no results. I use the Search all the time so I know I'm doing it right and I know this cannot be accurate.

For some reason the search won't accept anything under 4 letters..."Often" may not be specific enough for a search...

Common words like "often" are not indexed.
