Hi Shamik,
you could try solr grouping using group.query construct. you could discard
the child match from the result i.e. any doc that has parent_doc_id field
and use join to fetch the parent record
q=*:*&group=true&group.query=title:title2&group.query={!join
from=parent_doc_id to=doc_id}parent_doc_id:*&group.limit=10
Thanks,
Susmit
