Hi all, As far as I understand, SolrCloud currently does not allow the use of sorting by the pseudofield, score in the /export request handler (i.e., get the results in relevancy order). If we do attempt this, we get an exception, "org.apache.solr.search.SyntaxError: Scoring is not currently supported with xsort". We could use Solr's cursorMark, but this takes a very long time ...
Exporting results does work, however, when exporting result sets by a specific document field that has docValues set to true. Question: Does anyone know if/when it will be possible to sort by score in the /export handler? Research on the problem: We've seen https://issues.apache.org/jira/browse/SOLR-5244 and https://issues.apache.org/jira/browse/SOLR-8664, which are related to this issue, but don't fix it. Maybe I've missed a more relevant issue? Our use-case We are using Solrcloud in our team and it's added a huge amount of value to our users. We show a table of search results ordered by score (relevancy) that was obtained from sending a query to the standard /select handler. We're working in the life-sciences domain and it is common for our result sets to contain many millions of results (unfortunately). After users browse their results, they then may want to download the results that they see, to do some post-processing. However, to do this, such that the results appear in the order that the user originally saw them, we'd need to be able to export results based on score/relevancy. Any suggestions or advice on this would be greatly appreciated! Many thanks! Edd PS. apologies for posting also on Stackoverflow ( https://stackoverflow.com/questions/58167152/solrcloud-export-all-results-sorted-by-score) -- I only discovered the Solr mailing-list afterwards and thought it probably better to reach out directly to Solr's people (I can share any answer from this forum on there retrospectively).
