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 NumericField (expert: NumericTokenStream ).

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

Filter f = NumericRangeFilter.newFloatRange("weight",
            new Float(0.3f), new Float(0.10f),
            true, true);

accepts all documents whose float valued "weight" field ranges from 0.3 to 0.10, inclusive. See NumericRangeQuery<T> for details on how Lucene indexes and searches numeric valued fields.

NOTE: This API is experimental and might change in incompatible ways in the next release.
