Assuming that you have the Google toolbar, you can click on "Settings" at the far right where you'll find an "Options" button. The Options button will show you how to add a "Search only on current site" button to your toolbar. On mine, it looks sort of like a "magnifying glass with a handle" with a pair of "eyeballs" in the glass, and it's right next to the Google "Go" button.

Note that I'm looking at a "standard" Google toolbar in IE7. Your layout may vary some if you have a different browser or a different toolbar version.

There are "help" buttons splattered around in Google toolbar places, with one at the "Settings" button. If you poke around there, you should eventually find a way to "add search keys" and otherwise format the terms you type in the Google search box. SOME Boolian search forms can be used, and may be helpful sometimes. Just appending a +word or a -word will either find only results that include the word with the plus at the front and will EXCLUDE any results containing the word with a - in front. (Note that there IS NO SPACE between the + or - and the word followiing.)

The "form" for a search on a specific site is something like "searchterm site:mudcat.org." I'm not sure this is exactly the way you should do it, but it should be close enough for you to recognize it if you can find it in Google help. I dont' use the "manual form" much so I'd have to dig into stuff to find an exact script for you. (I've already got the button up.)

I've found the Google toolbar quite helpful, but would caution against going overboard with adding "lots of extra buttons." Try to figure out what will be helpful for your methods of searching and ignore some of the others.

Google also has quite a few "other accessories." Mostly I find them "underwhelming" and don't use many of them except for special situations.
