I currently have a database that collects forums posts from my site. I would like to have some system when I can get a pulse on what people are talking about by running a query on my field "First Post" that has the body of the first post of the thread. I could run a query by predetermined keywords but ultimately I want something that would find the frequency of any word above a character size of 5 or so.
Does anybody have some experience with a query like this or would be able to get me pointed in the right direction?
