This is exactly the behavior I'd expect. Consider what would happen otherwise. Say you have documents with the following values for a field (call it blah). some data some data I put in the index lots of data data
Then I don't want deleting on the term blah:data to remove all of them. Which seems to be what you're asking. Even if you restricted things to "phrases", then deleting on the term 'blah:some data' would remove two documents. So, while UN_TOKENIZED isn't a *requirement*, exact total term matches *is* the requirement. By that, I meant that whatever goes into the field must not be broken into pieces by the indexing tokenizer for deletes to work as you expect.

I'm having several problems with deleting documents with Lucene 2.2. Via the IndexWriter, I can successfully delete a document by its primary key via a Term, but ONLY if the field was stored as Field.Index.UN_TOKENIZED. If it was stored as TOKENIZED, the debug output says it is deleting the document, but subsequent searches executed against terms that existed only in the original document (and not the one I add to replace it) still return the deleted document. (Searches against terms only in the new document will return the new document.) Another problem is that if I first delete the document using deleteDocuments(Term) and then add a new document that happens to have identical fields to the one I deleted, the new document is not added. Of course this operation is fairly wasteful, but it seems like the new document should replace the old one, even though they're the same. This happens even if I perform a flush() after the delete and before the add. It will also happen even if I flush, close the IndexWriter and create a new IndexWriter. It seems that once a document with a particular set of fields has been deleted, an identical one can never be re-added. Any pointers or things I should check or more detailed information I can provide to track this down? Nick -- "Courage isn't just a matter of not being frightened, you know.
