QueryParser uses the given Analyzer when constructing they query, so it will never hit a NOT_ANALYZED term. In general, it is a bad idea to use QueryParser on fields that are not analyzed. There are two possibilities to solve the problem:
- Instantiate the query to match the not-analyzed (but indexed field) directly as a TermQuery. - Use a PerFieldAnalyzerWrapper and choose a specific analyzer for this field that does not touch your names (e.g. KeywordAnalyzer). Use this wrapped analyzer for the both searching an indexing (and use Field.Index.ANALYZED!).
