I must be missing something :) a) We're not a freaking database, why the constant attempts to compare ourselves to it / mimic some functionality? b) The criteria to define the set of deleted documents can already be expressed as a query - IndexWriter.deleteDocuments(query). So what I am offering is to preserve the way to point at the docs we want to see deleted, and allow to do partial modifications on them. Thus we add new and exciting functionality, while introducing zero new concepts.
