Searching the site

Have tried to search the site, including for an answer to this(!), but everytime I search I get "You must include at least one positive keyword with 3 characters or more."
What does this mean???

I get this too. And have for a few days. Thought it might just be me. I have sent j-b-m (our great leader) a message about this.

Search is working again. Looks like the site has been upgraded. The Forum has a slightly new look and feel.
