For a given factory, each query analyzer chosen should be of the same type, and it should match the result of LuceneAnalyzerFactory.getName(). Call LuceneAnalyzerFactory.getIndexAnalyzerChooser(Index) before calling this method, and use its return for the argument indexAnalyzerChooser. No need to override this method if StandardAnalyzer is to be used for query time. Override this method to customize the analyzer for query time, or directly return the indexAnalyzerChooser instance, if it is used for both indexing and query time.
