Google recently introduced the customized search feature. This allows you to basically decide what sites a particular search page is going to search across. You can use to add in particular keywords to every search and/or select which webpages are crawled.
Lets say, for example, that you are interested in kinases. You could choose 20 or so sites that you regularly check out and add them to your kinase customized search engine. Then you, or anyone else who you give the URL to, can search across just those sites.
What’s the advantage – well if you commonly search for a common term and get false drops then limiting what you are searching will help.
Anyway, here’s my attempt at a kinase site…(first pass, probably needs some refinement…)
