You can index comments as child records. The structure of the Solr document should be able to incorporate both parents and children fields and you need to index them all together. Then, just search for JOIN syntax for nested documents. Also, latest Solr (4.9) has some extra functionality that allows you to find all parent pages and then expand children pages to match.
