Hi all. I'm trying to implement a form of document deletion where the previous versions are kept around forever ( a primitive form of versioning) but excluded from the search results.
I notice that after calling IndexWriter.deleteDocuments, even if you close and reopen the index, the documents are still accessible using document(int) but are returned from queries, which is exactly the behaviour I want. However, if I call optimize() they will obviously be obliterated. My question is: as long as I never call optimize() -- will the deleted documents hang around forever, or will a merge due to adding the new documents eventually cause them to be removed? If they will be removed then I need some other way to avoid them being returned. I was thinking of actually *not* deleting them, but maintaining a giant filter - I could store this filter on disk but it's going to be pretty large even if I use a BitSet. :-( Is there any other way to go about it?
