I've put up a dataset on Github that maps popular search terms to bills in Congress. It's a simple, 5-column CSV designed to help people create better search engines that take in user input to search for bills. The idea is that this will be useful to, and get contributions from, the community of people out there working with legislation and building tools around them.

It's humble - I started it out with a mere 7 rows, assigning the keywords "Obamacare", "SOPA", "PIPA", and "PPACA" to the appropriate bills. There are certainly more good candidates than that, so please contribute via pull request, or if you don't know how to do that, open an issue and talk about it with words.
