A search tip: If you use QUOTATION MARKS when typing in more than one word, the search engine will find that phrase, not just the two words. "Backstay adjuster" obtains results for that phrase. Backstay adjuster finds results for both the words backstay and adjuster, which is probably not what you're searching for.
ADVANCED SEARCHING TECHNIQUE
In addition to the suggestion above, you can do an advanced search which includes the word or phrase you are searching for AND the name of the author.
You do this by using the "SEARCH" feature that is accessed on the strip of features just below the right hand search box. This starts with Home, Help, Search, Admin, Profile, etc.
Click on that search and you get a new dialog box that shows both search phrase and author. The author needs to be the screen name of the registrant. That's another reason why we suggest using your real name...
A neat feature is it remembers the phrases and the names, saving some typing for later searches.
The wiki also has a good search engine.
