PerFieldAnalyzerWrapper

This analyzer is used to facilitate scenarios where different fields require different analysis techniques. Use the Map argument in PerFieldAnalyzerWrapper to add non-default analyzers for fields.

Example usage:

{@code
Map analyzerPerField = new HashMap<>();
analyzerPerField.put("firstname", new KeywordAnalyzer());
analyzerPerField.put("lastname", new KeywordAnalyzer());

PerFieldAnalyzerWrapper aWrapper =
new PerFieldAnalyzerWrapper(new StandardAnalyzer(version), analyzerPerField);
}

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.
