Dear Solr users,
We are upgrading from solr 4.x to solr 6.5 and one important part of it is to implement json API in our application. Our facet query uses group.facet, in order to support this we have used facet aggregation function 'unique(myField)' to get the unique count. After doing the update we are getting strange results in which the count (uniqueCount) for the first facet bucket is correct and the remaining are either 0 or incorrect. Below are the both the solr query urls for reference : Old http://wwwdev.ebi.ac.uk/pdbe/search/pdb/select?group=true&group.field=pdb_id &group.ngroups=true&group.facet=true&facet=true&rows=0&facet.limit=100&facet .mincount=1&facet.sort=count&json.nl=map&facet.field=detector&facet.field=ex perimental_method&facet.range=deposition_year&f.deposition_year.facet.range. start=1970&f.deposition_year.facet.range.end=2050&f.deposition_year.facet.ra nge.gap=5&f.deposition_year.facet.range.other=between&f.deposition_year.face t.range.include=upper&q=text%3Ahemoglobin&wt=json&indent=true New (json api implementation) http://wwwdev.ebi.ac.uk/pdbe/search/pdb/select?json={query:%20%22text:hemogl obin%22,%20facet:%20{%20detector:%20{type:%20%27terms%27,%20field:%20%27dete ctor%27,%20limit:%20100,%20mincount:%201,%20sort:count,%20facet:%20{%20uniqu eCount:%20%22unique(pdb_id)%22%20}%20},%20experimental_method:%20{type:%20%2 7terms%27,%20field:%20%27experimental_method%27,%20limit:%20100,%20mincount: %201,%20sort:count,%20facet:%20{%20uniqueCount:%20%22unique(pdb_id)%22%20}%2 0},%20deposition_year:%20{%20type:%20%27range%27,%20field:%20%27deposition_y ear%27,%20start:%201970,%20end:%202050,%20gap:%205,%20other:%20%27between%27 ,%20include%20:%20%27upper%27,%20limit:%20100,%20mincount:%201,%20sort:count ,%20facet:%20{%20uniqueCount:%20%22unique(pdb_id)%22%20}%20}%20}%20}&rows=0& wt=json&indent=true Am I missing something in the new facet json api query or it is a solr issue ?
