Hi Alvaro, We had thought about this. But our requirement is dynamic. The 4 fields to pivot on would change as per the many requirements. So, this will need to be handled at query time.
Just considering the Endeca equivalent, it looks easy there. If this feature is not available on Solr, would there be any effort in building this one? P.S. The endeca equivalent query below: RETURN Results as SELECT Count(1) as "Total" GROUP BY "Country", "State", "part_num", "part_code" ORDER BY "Total" desc PAGE(0,100) -Lewin -----Original Message----- From: Alvaro Cabrerizo [mailto:topor...@gmail.com] Sent: Friday, February 19, 2016 1:02 AM To: solr-user@lucene.apache.org Subject: Re: Hitting complex multilevel pivot queries in solr Hi, The only way I can imagine is to create that auxiliar field for performing the facet on it. It means that you have to know "a priori" the kind of report (facet field) you need. For example if you current data (solrdocument) is: { "id": 3757, "country": "CountryX", "state": "StateY", "part_num: "part_numZ", "part_code": "part_codeW" } It should be changed at index time to: { "id": 3757, "country": "CountryX", "state": "StateY", "part_num: "part_numZ", "part_code": "part_codeW", "auxField": "CountryX StateY part_numZ part_codeW" } And then perform the query faceting by auxField.
