Class PrefixCodedTerms

java.lang.Object

org.apache.lucene.index.PrefixCodedTerms

All Implemented Interfaces:

Accountable

public class PrefixCodedTerms
extends Object
implements Accountable

Prefix codes term instances (prefixes are shared). This is expected to be faster to build than a FST and might also be more compact if there are no common suffixes.

NOTE: This API is for internal purposes only and might change in incompatible ways in the next release.
