Allow maximum hits returned to be configurable.
...
This obviously has a performance impact, but it might not be a big deal for most people and is now left to their discretion. The default of 500 results stays to maintain backward compatibility.

...
Instead of ignoring a duplicate blindly, ignore when match score is less than existing key.

Short circuit to speed up single token searches.
...
- Refactor token position population
- Store only the query index in topster instead of storing the full offsets.
- Calculate the offsets finally on the results that are to be returned.
