grouping - Solr facet with sub facets -


i'm trying find solution make subfacet list facets.

i have clothes size on products , stored in solr

"size_both":"w30l30", "size_width":"w30", "size_length":"l30"

i wish generate list of subfacet each width:

  1. w30 (8)

    • l30 (3)
    • l32 (1)
    • l33 (4)

  2. w32 (2)

    • l30 (1)
    • l34 (1)

etc

anyone know how accomplish this? thought group, didn't work.

use facet pivoting achieve desired result:

facet pivoting

try below query:

http://<host_name>:<port>/solr/<core_name>/select?q=*:*&rows=20&wt=json&indent=true&facet=true&facet.pivot=size_width,size_length
