I didn't describe the context fully. The app is a server that recieves updates randomly a couple of hundred times a day and I want the index to be updated at all times. If I would recieve several updates at once I could batch it but that is quite unlikely.

Do as I wrote: > If you need to update lots of documents in your corpus (delete and > add) then first delete the documents with the reader, close it and add > them again with the writer.

So something like this instead: > IndexReader reader = new IndexReader(dir); > for (MyDocument doc : myDocuments) { > reader.deleteDocuments(new Term("id", id); > } > reader.close(); > IndexWriter writer = new IndexWriter(dir, analyzer, false); > for (MyDocument doc : myDocuments) { > writer.addDocument(luceneDocFactory(doc)); > } > writer.close(); > setSearcher(new IndexSearcher(dir)); --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
