public class CompareStringQuery
extends CompareQuery<String>

A Lucene Query implementation that is used to apply a Comparison constraint against a string field. This query implementation works by using the weight and scorer of the wrapped query to score (and return) only those documents with string fields that satisfy the constraint.
