Caster

Text search engine based on Sonic. This was originally for a video search engine. I needed something that could index fast and was lightweight.

Client is here: Caster Ruby.

One major issue is the app will hash strings into 32bit ints and collisions are fairly common. I would recommend upgrading this to use 64bits.

I'm releasing this for the Crystal community to learn from and extend.
