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(IndexReader, String, String, boolean, boolean)
.
A similar class is org.apache.lucene.search.DocValuesRangeQuery
in the sandbox module. That one is
constant scoring.(constant scoring)
