-----------------------------
Hi!
I trying use this feature with solr nightly build: i add __root__ field and
index data with inner <doc> blocks.
?q=*:* gives me data:
<result name="response" numFound="2" start="0">
<doc>
<int name="id">4</int>
<bool name="is_parent">false</bool>
<int name="_root_">3</int>
</doc>
<doc>
<int name="id">3</int>
<bool name="is_parent">true</bool>
<long name="_version_">1447068567577034752</long>
<int name="_root_">3</int>
</doc>
</result>
?q={!parent which=is_parent:true}*:*
gives me error:
child query must only match non-parent docs, but parent docID=1 matched
childScorer
however ?q={!child of=is_parent:true}*:*
gives me expected result (only one child doc):
<result name="response" numFound="1" start="0">
<doc>
<int name="id">4</int>
<bool name="is_parent">false</bool>
<int name="_root_">3</int>
</doc>
</result>
Please, can you explain me what i doing wrong?
