we need to use binary DocValues (in a customized collector) added during indexing, i first tested in standard TopScoreDocCollector, it seems that we need to:
LeafReaderContext => reader() => get binary iterator => advanced to correct location Is this the correct way or actually we have a better API (since we already in that docId it seems to me that the binary DocValues should be readily available? Also do we have a way to see directly indexed data (Luke seems obsolete, Marple does not work with lucene 7.4.0 yet)? Thanks very much for helps, Lisheng
