help with doing a search?

How can I do a multiple-word search, for example, "red light switch", and have only those posts appear with that phrase, rather than each single word. Sorry, can you tell I'm not very knowledgeable? Also, who can I ask such questions of in the future?

Use the advanced search box and put the search phrase in quotation marks.

Oh, thanks a lot! Works like a charm! So simple when you know how, hey?
