Hi Paul, Hah! Yes, it's the former I think... The "Hah!" was because I was googling, and just ran across this: http://javatechniques.com/blog/lucene-in-memory-text-search-example/ which, I think, creates an in-memory index, then searches it. I was reading through that, as I saw your message. As I was reading though, I am wondering: This seems like it would create an awful lot of overhead? In other words: - I'd have to create a (very small) index, for each sub-document, where I do the Document.add() with just the (for example) two terms, then - Run a query against the 1-entry index, which - Would either give me a "yes" or "no" (for that sub-document) As I said, I'm concerned about overhead. Some of the documents are quite large, containing >20K sub-documents. That means that, for such a document, I'd have to create >20K indexes. Is there really no other way to do this? I guess that, in my mind, I keep thinking about somehow "redirecting" Lucene to do a search on a single String object (that was just a kind of metaphor)? Comments? Thanks for your response!
