public class ConstantScorePrefixQuery
extends Object

Creates PrefixQuery instances that doesn't rewrite into a BooleanQuery with all matching terms in the field. This query returns a constant score equal to its boost for all documents with the matching prefix term.

This can be significantly cheaper and faster if there are a lot of matching terms. It is very slightly slower if the number of matched terms is one or two.
