The search tool is simple to use, has a 3 character minimum, so type a search word (or number, i.e. 416) and read through any results. If you go to a section first, for example Advice & Tecnical Help, Electric Guns and select serch in "this forum" it will narrow down the number of hits to make it easier to read results. Then change sub-forum and run search again.
