Hi Eleanor.
In my Lucene index there's a field that contains the local names of XML elements, one name per document. Users can enter arbitrary queries for this field, so I'm using a QueryParser.
From reading around it looks as if the field needs to be tokenized, but since the field's content is always a single term, is this really necessary?
You are right, your field is already tokenized, but from what I know the main difference is that untokenized fields do not pass your selected analyzer when being added to the index. If your analyzer for example incorporates the LowerCaseFilter, the field will be converted into lower case before it is indexed. When using the same analyzer for your QueryParser this will allow you to perform case insensitive query.
If you add the field untokenized and your Analyzer (at query time) incorporates the LowerCaseFilter, you will be unable find elements that contain upper characters.
