public class OLucenePerFieldAnalyzerWrapper
extends org.apache.lucene.analysis.DelegatingAnalyzerWrapper

Created by frank on 10/12/15.

Doesn't allow to wrap components or readers. Thread local resources can be delegated to the delegate analyzer, but not allocated on this analyzer (limit memory consumption). Uses a per field reuse strategy.
