Basically added analyzerFactory to create analyzers easier and SimpleIndex (name tbd) enabling users to give the fields within their index a type (like int, float, double, ..) to make range queries possible.
A custom type is date, which converts dates to longfields which may be used in range-queries.

Querying should also be easier. Have a look at my dirty little test.js (i know .. yuk, but it describes parts of what is possible)
