Hi, I was wondering if the addIndexes() method in IndexWriter can be used for updating documents.
Specifically, I'd like to leave my primary index alone during the update process. Instead, I want to use a separate index (on a RAMDirectory), and to make the updateDocument() calls on it and finally to merge the changes to the primary index. This leads to several questions: 1) If I make an updateDocument call and the document isn't present in the separate index, will it fail? 2) After I merge the indeces, will the documents in the primary index be updated (i.e. deleted and then added if existing, otherwise just added)? 3) If the merge does update the primary index, does it all occur in a single transaction? Thanks for the help! Moti
