Hi Jack, for the point: "each element of the array as a solr document, with a group field and a disease field" Did you mean it this way:
<doc> "group1_grp": G1 "disease1_d": 2, "disease2_d": 3, </doc> <doc> "group1_grp": G2 "disease1_d": 2, "disease2_d": 3, "disease3_d": 1, "disease4_d": 1, </doc> similar to first case: having dynamic fields for disease? Will it be performance issue if disease field increase to millions?
