Creating Google Custom Search Engines is not as hard as you might think. To create a simple search engine, go to
http://www.google.com/cse/, name your engine, add links to search, optionally add links to avoid, and you may get a useful tool. There are more advanced techniques, but even this much gives you nice control over search results, without the need to retype your search strings.
Did you know you can email a custom search engine to a colleague? Google provides us with a piece of HTML source code to include on a site, which you can also just save as an HTML file. You can then email it to someone as an attachment. If you have a team of sourcers, it's a nice way to share searching techniques.
Take a look at the file I have attached to this post and guess what it searches. :)
Experts - can you guess which two links are included and which one link is excluded in it?
