Hi,
I am working on a query that must return parent docs and facet on both the
parent and child fields. Here's a sample doc-
<doc>
<field name="id">1</field>
<field name="name">merc</field>
<field name="type">car</field>
<field name="user">sagandhi</field>
<field name="child_id">2</field>
<field name="child_id">3</field>
<field name="doc_type">parent</field>
<doc>
<field name="id">2</field>
<field name="doc_type">child</field>
<field name="class">S</field>
<field name="color">blue</field>
</doc>
<doc>
<field name="id">3</field>
<field name="class">Z</field>
<field name="code">25</field>
<field name="doc_type">child</field>
</doc>
</doc>
I want to search for "merc" or "*" and return facets for type/user from
parent docs, and code/color from child docs. Currently I am not using
blockjoin. Instead I make two queries, one on the parent docs and the other
on the child docs. I get the applicable child_id from the first query and
feed it into the second query to get the child facets.
However this has impacted performance and is not scalable if the child_ids
I get are huge. Is there a way to combine the two queries using block join.
I tried this query -
q=*:* &fq=user:sagandhi &fq={!parent
which="doc_type:parent"}color:blue&facet.field=type&child.facet.field=code
I get this error - Block join faceting is allowed with
ToParentBlockJoinQuery only
Am I missing something here? Any pointers please.
Thanks,
Soham
