Support field-based analysis

See original GitHub issue

In Lucene , we have the ability to analyze different fields using different analyzers. As initiated in #156 , next natural step should be to support different analysis depending on the field.

Example using Lucene Core :

Map<String, Analyzer> analyzerPerField = new HashMap<>();
analyzerPerField.put("firstname", new StandardAnalyzer());
analyzerPerField.put("address", new WhitespaceAnalyzer());

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

IndexWriterConfig config = new IndexWriterConfig(aWrapper);

More information : PerFieldAnalyzerWrapper

I need to add a few more unit tests on this and then release it.

This feature request is valid.

Do you have any proposal on how the API will look like?

As a first draft, I think about passing a Map[String,String] where keys are field names and values are the class name of the analyzer, ie. org.apache.lucene.analyzer.EnglishAnalyzer. Note: values are string so that they are serializable. WDYT?
