Can we change to search engine to allow small words? I'm not sure what good disallowing small words does, but there are alot of really nice words that are small.....rot, gas, cap, ac, a/c, dc, btu, bed, tow, eat, air, psi, etc., that would be useful to search, but cannot. I've done several searches that have 20 pages of results, but had I been able to search a smaller word, it would have cut down the results to just a few pages. Is it possible/easy to do?
