I think this is limited by... ... not being able to [easily] add new fields over time... you'd have to reindex all documents (to insert the new magic token) just to add a new field. ... requiring additional manipulation for appendable, updateable fields... when you append new data to a field, you'd have to go in and remove the special token. --tim --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org
