Craig, another hint would be to use plus and minus signs in your search query, or a phrase in quotes.
A plus sign preceding a word tells the search that the word must be included, and a minus sign that the word is excluded.
Example +distributor +grooves yielded 9 results, with your answer in the thread on the first hit.
Without the + signs: distributor grooves (no quotes) yielded 40 pages! with a bunch of other unrelated stuff. I got to page 6 without finding the top result on the first search.
In this particular case "distributor grooves" got no results.
[on edit] For those following along in this thread, Rustoholic has put together a comprehensive post on how to use the Advanced Search
HERE. It's in a sticky thread in the IT Short Bus forum.
Edit more (by Peggy): so we moved it to go along with Dean's post to give a little testimonial of sorts.
