-/**
- * This analyzer is used to facilitate scenarios where different
- * fields require different analysis techniques.  Use {@link #addAnalyzer}
- * to add a non-default analyzer on a field name basis.
- * 
- * <p>Example usage:
- * 
- * <pre>
- *   PerFieldAnalyzerWrapper aWrapper =
- *      new PerFieldAnalyzerWrapper(new StandardAnalyzer());
- *   aWrapper.addAnalyzer("firstname", new KeywordAnalyzer());
- *   aWrapper.addAnalyzer("lastname", new KeywordAnalyzer());
- * </pre>
- * 
- * <p>In this example, StandardAnalyzer will be used for all fields except "firstname"
- * and "lastname", for which KeywordAnalyzer will be used.
- * 
- * <p>A PerFieldAnalyzerWrapper can be used like any other analyzer, for both indexing
- * and query parsing.
