Google Greatness: Searching Specific Sites

Here's a tip I read on an Adobe blog that solves one of those niggling problems you have when searching the internal content of a site for something particular.

Suppose, for the sake of argument, you wanted to see how much secondhand Canon 500 mm f4 lenses were going for in the buy/sell pages on a large site such as Fred Miranda. You could a) use the search box on that site and find that it's largely worthless or b) type the following into a Google search box:

site:http://www.fredmiranda.com Canon 500

Note the "site:" syntax at the beginning because that's the magic sauce. And guess what? It works. Very well indeed. (Alas, resulting in the knowledge that they are still running around $5,000, or roughly 10% to 15% below retail.)
