Hallo, If you do not analyze fields during indexing, you cannot really use QueryParser on the search side (because the QueryParser itsself always analyzes the entered query string).
If you added some fields using NOT_ANALYZED, just use a simple "new TermQuery(new Term(field, term))" to search for them. This is simplier and does not analyze. If you are creating such queries programmatically and have special "id" fields, it is the classical case for TermQueries. Or, as Robert said, use an Analyzer, but use a special one, not corrupting your ASINs.
