Add stemming for technical terms

I want to get everything about angular just by searching for angular, not angular | angular.js | angularjs – these all should be equivalent.

PostgreSQL supports search dictionaries, those should be useful: http://www.postgresql.org/docs/9.1/static/textsearch-dictionaries.html

How to get a list of technical terms? Get a list of words from HN comments that are not in the English dictionary, but are mentioned many times on github/stackoverflow? Actually, maybe use stackoverflow's tags or something? Or github project names?
