It's not full-text search, it's specifically a very limited search space (tags), which is why Redis is likely a very good solution to this problem.

Oh really? I thought PostgreSQL full text search was pretty feature complete. I just didn't want to pay for extra space... and to play with Redis.

However my implementation wasn't feature complete either. IT was literally as you just said, tags. Never had time to add more search operations on it. https://github.com/seivan/Rfizzy
