Class NumericRangeFilter<T>

A Filter that only accepts numeric values within a specified range. To use this, you must first index the numeric values using Int32Field, SingleField, Int64Field or DoubleField (expert: NumericTokenStream).

You create a new NumericRangeFilter with the static factory methods, eg:

Filter f = NumericRangeFilter.NewFloatRange("weight", 0.03f, 0.10f, true, true);

Accepts all documents whose float valued "weight" field ranges from 0.03 to 0.10, inclusive. See NumericRangeQuery for details on how Lucene indexes and searches numeric valued fields.
