public class FunctionRangeQuery extends Query
ValueSource
that matches docs in which the values in the value source match a configured
range. The score is the float value. This can be a slow query if run by itself since it must visit all docs;
ideally it's combined with other queries.
It's mostly a wrapper around
FunctionValues.getRangeScorer(Weight, LeafReaderContext, String, String, boolean, boolean)
.
A similar class is org.apache.lucene.search.DocValuesRangeQuery
in the sandbox module. That one is
constant scoring.(constant scoring)

works properly.
Typically a query will be equal to another only if it's an instance of
the same class and its document-filtering properties are identical that other
instance. Utility methods are provided for certain repetitive code.equals
