Of course I would not search Armstrong Bicycles because logically there is a lot of postings that would fit that description including the armbands. If I were interested in Armstrong Bicycles I would probably search Armstrong Trek or Armstrong cm. You have to think like a computer a bit and use search word combinations that would not be common to anything but what you are looking for. If I am looking up Simplex derailleurs I would not just put Simplex or you would get overwhelmed. I do not use the whole word derailleur as some may not spell it that way. I don't use plurals as leaving them off captures them and ones without. Try this for fun. Search for Simplex then try Simplex Derail* where the * is a wildcard and see what happens. You will begin to get the feel for what I mean.
