I'm not sure what you mean by "category bits". Can you possible
implement the categories like this;
sport/
sport/shooting/
sport/fishing/
sport/fishing/fly
sprot/fishing/deep_sea
etc.
Then, lets say you have a query in query_str. You can get all results
in the sport category like this;
index.search_each(query_str + "AND category:sport/*") {
# ...
}
You can get all results in the fishing category like this;
index.search_each(query_str + "AND category:sport/fishing/*") {
# ...
}
Am I making sense?

You've lost me. Could you give some example code?

I'll explain filtering once I understand better what it is you are trying to do.
