Yonik Seeley updated SOLR-10657:
--------------------------------
Description:
A contrived example... facet by user, and then have that users reviews as a
sub-facet. For each bucket, the join.to (user) field will have a single exact
value and the join query can be optimized to a field query.
[code}
myfacet : {
type: terms,
field : user,
facet : {
genres : {
type: terms, field:genre
domain : { join:{from: user, to: review_user} },
}
}
{code}
Related: another thing I've thought about in the past is ways to use the
current bucket "value" (or a parents bucket value) in queries for example. A
late-binding context sensitive term query (or query parser) is one potential
way to implement some of this.
