Faceting on both Parent and Child records in Block Join Query Parser
Hi,
Is it possible to do nested faceting on both records in parent and child in
a single query?
For example, I want to facet both author_s and book_s. Author is indexed as
a parent, whereas Book is indexed as a child.
I tried the following JSON Facet query, which is to do a facet of all the
list of author (in the parent), followed by a facet of all the list of
books (in the child) that are written by the author.
http://localhost:8983/solr/collection1/select?q=*:*
&json.facet={
items:{
type:terms,
field:author_s,
facet:{
by1:{
type:terms,
field:book_s
}
}
}
}
}&fl=null&rows=0
However, it only managed to return me the facet of the list of author. I
could not get any results for the list of books. Is this possible to be
done, or what could be wrong with my query?
Regards,
Edwin

I _think_ what is happening is that you are going in both parent and
child directions in your filters.
Try making your query ('q') define your original domain
(q=type_s:author) and then 'books' goes inside the parent "author"
scope and that's where you change your domain.

Alex.

Edwin,
It seems like you try to pull document hierarchy back. That's usually done
by searching parents and fl=[child ..],,.

Some of the sample documents are like the following:
Author is the Header, while Books are the Child
Author: Edwin
Books: Book 1
Book 2
Book 3
Author: John
Books: Book 4
Book 5
For this query:
http://localhost:8983/solr/collection1/select?q=*:*
&json.facet={
author:{
type:terms,
field:author_s,
domain: { blockParent : "type_s:author" }
},
books:{
type:terms,
field:book_s,
domain: { blockChild : "type_s:book" }
}
}&fl=null&rows=0
I'll get the following results:
"facets":{
"count":2,
"author":{
"buckets":[{
"val":"Edwin",
"count":1,
"books":{
"buckets":[]}},
{
"val":"John",
"count":1,
"books":{
"buckets":[]}},
I can't manage to get the list of books to be displayed in the buckets for
books.

Edwin

Perhaps show a couple sample documents, and then what data you're
looking for in a response?
This stuff can be tough to pin down without concrete examples.

&json.facet={
items:{
type:terms,
field:author_s,
domain: { blockParent : "type_s:author" },
facet:{
by1:{
type:terms,
field:book_s,
domain: { blockChild : "type_s:book" }
}
}
}
}
}&fl=null&rows=0
Only when I didn't use the nested method, but query it individually like
the one below, the I managed to get the result.
http://localhost:8983/solr/collection1/select?q=*:*
&json.facet={
items:{
type:terms,
field:author_s,
domain: { blockParent : "type_s:author" }
},
by1:{
type:terms,
field:book_s,
domain: { blockChild : "type_s:book" }
}
}&fl=null&rows=0

Re: Faceting on both Parent and Child records in Block Join Query Parser

You need to switch the domain to the child records. It is somewhere in the
guide or Yonik's blog linked.
