I'm adding Documents in batches to an index with IndexWriter. In certain
circumstances, I do not want to add the Document if it already exists, where
existence is determined by field id=myId.
Is there any way to do this with IndexWriter or do I have to open a reader and
look for the term id:XXX? Given that opening a reader is expensive, is there
any way to do this efficiently?
I guess what I want is
IndexWriter.addDocumentIfMissing(Term term, Document doc, Analyzer analyzer)
Thanks
Antony
