Hi, If an update to a non-existent dv field is attempted, IndexWriter throws an exception: "can only update existing numeric-docvalues fields!".
This exception is thrown after checking with the globalFieldNumberMap (which is obtained from the SegmentInfos). Is there a way, given an IndexWriter instance, I can obtain a list of fields that have been indexed through this writer (so that I can check before attempting to update a non-existing DV field)? In absence of something that I'm missing that exists already, is it possible to expose either the segmentInfos or the globalFieldNumberMap as a public API? Regards, Ishan
