Search Function Improvements

[FordNut]

It would be nice if the search function didn't eliminate 3-character searches. There are lots of TLA's that are used on the MM (BAP, MAF, EGR, TPS, JLT, etc) and it would be nice if we could search for these terms. Maybe the basic search could limit to 4+ and advanced search could use 3+ characters?

Also, it would be nice if subsequent searches were allowed in order to drill down to a specific topic by allowing a new search to specify "search within results".

I've been able to do 3 character searches. Just did some of the examples you listed and it seemed to work.
