Part of the problem is that some words are used over and over again, and come up in all kinds of discussions, like twins, single, kicker, trailer, radar, GPS, electronics, antenna, wiring, bulkhead, fuel, tank, gunnel, anchor, rode, etc., and make searches within that word topic much more difficult.
To the extent that it's possible, it's always useful to narrow the search down by putting in a more or less unique word which will at least somewhat only be found in the discussions you're looking for, such as Garmin, SeaStar, Dickinson, EPIRB, Sirius, Flathead (Lake), Apalaciacola, blisters, coaxial, searchlight, handrail, LED, etc.
You can also go to the Forums, look at the topical layout/classification scheme, and scan and then search the list of discussion threads within the most obvious topic area.
The search engine can also be directed to look only within certain Forum topics, so as to not come up with random usage hits all over the place.
Note this from the Search Engine page:
"Search for Keywords:
You can use AND to define words which must be in the results, OR to define words which may be in the result and NOT to define words which should not be in the result. Use * as a wildcard for partial matches."
Thus if you use
single and twins and kicker
you get 15 hits on one page that all refer to the subject you want. Try it. (I couldn't make a link with the contained input information.)
It also helps to read through the interesting topics in the Library Forums with spare time, to read as much of the discussion traffic here on the site as you can, and remember what you've read and who said it to whatever degree possible.
Hope this helps!
