We have an index of 14 million records(2.5TB). We have been successful in reindexing all of them but 80K docs. Those are spread around different dates. Our documents are from 1980 to present. We figured out that missing documents are spread around only 500 dates. How to reindex only those missing documents without having to reindex all over again. is there a way to specify all those dates together (not range).
