Hi everyone,
We have two multi-valued fields, both containing usernames, and we'd like to
compute the combined counts across both fields. For example, if we were to
facet on these two docs:
doc1: { field1: [user1, user2], field2: [user3, user4] }
doc2: { field1: [user1, user3], field2: [user2] }
we'd expect the following counts:
user1: 2
user2: 2
user3: 2
user4: 1
I know one option is to create a new field that combines the two and facet on
that, but these lists can be large and we could have millions of unique users,
so we're looking at implementing a custom facet processor to avoid duplicating
data. Looks like one way would be to subclass SimpleFacets and register a new
FacetComponent, but this seems to use the legacy faceting methods. Is there a
way to do something similar with the JSON API? Is this even advisable?
Thanks,
Julia
