If you find yourself searching the same sites and using the same criteria over and over, you can simplify things and save yourself a lot of time by using Google's Custom Search.
The feature, which can be found here, started as a service to give webmasters the ability to embed a Google search box that searches their webpage. But even if you don’t have a site you need to index, search, and serve ads against, Google Custom Search can be a powerful tool for any workflow that queries the internet.
