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.

Example usage:

            PerFieldAnalyzerWrapper aWrapper =
            new PerFieldAnalyzerWrapper(new StandardAnalyzer());
            aWrapper.addAnalyzer("firstname", new KeywordAnalyzer());
            aWrapper.addAnalyzer("lastname", new KeywordAnalyzer());
            

In this example, StandardAnalyzer will be used for all fields except "firstname" and "lastname", for which KeywordAnalyzer will be used.

A PerFieldAnalyzerWrapper can be used like any other analyzer, for both indexing and query parsing.
