Hi Lucene community, Our users could do very heavy searches and they are able to change the sorting criteria multiple times after getting the results. We collect all of them, this is important for our use case, disabling scoring if the result size is too large to make the search faster. Currently we have our own multi-thread sorting code using DocValues (one instance per thread) to do this after the results are returned, so we don't have to run the heavy searches again.
We are upgrading from Lucene 6.6 to 7.x and DocValues access is not random anymore, but our custom sorting code was based on that. So we are considering to stop using custom sorting and to use internal Lucene sorting, but we need to change the sorting multiple times after getting the TopDocs results. Is this possible? I searched the docs, but was just able to find out how to sort at the same time the search is done using IndexSearcher.search(..., Sort) methods. Thanks in advance, Luís Nassif
