Question: Does anyone know of any open source search projects written in Go?

I want to implement a simple site search for my site and am looking for a web crawler, but more specifically, a search algorithm written in Go.

Any ideas, projects, or suggestions?

Answer: 
The code ended up working, it was hardware issue with the connections from the flowmeter (>.>)
The reason the numTicks variable is not changed is probably due to the interrupt not triggering. You should put a breakpoint in count() to confirm this. Then you need to figure out why the interrupt isn't triggering as it should, but that is another question.
