Mikhail Khludnev commented on SOLR-5285: ---------------------------------------- Hello Varun, You can experiment with the following code: {code} @Override public void transform(SolrDocument doc, int docid) throws IOException{ parentid = doc.getField("id"); children = searcher.getDocList( QParser.getParser("{!child of=content_type:parentDocument}id:"+parentid).getQuery(),...); doc.put("children", children); } {code} > Solr response format should support child Docs > ---------------------------------------------- > > Key: SOLR-5285 > URL: https://issues.apache.org/jira/browse/SOLR-5285 > Project: Solr > Issue Type: New Feature > Reporter: Varun Thacker > Fix For: 5.0, 4.6 > > > Solr has added support for taking childDocs as input ( only XML till now ). > It's currently used for BlockJoinQuery. > I feel that if a user indexes a document with child docs, even if he isn't > using the BJQ features and is just searching which results in a hit on the > parentDoc, it's childDocs should be returned in the response format. > [~hossman_luc...@fucit.org] on IRC suggested that the DocTransformers would > be the place to add childDocs to the response. > Now given a docId one needs to find out all the childDoc id's. A couple of > approaches which I could think of are > 1. Maintain the relation between a parentDoc and it's childDocs during > indexing time in maybe a separate index? > 2. Somehow emulate what happens in ToParentBlockJoinQuery.nextDoc() - Given a > parentDoc it finds out all the childDocs but this requires a childScorer. > Am I missing something obvious on how to find the relation between a > parentDoc and it's childDocs because none of the above solutions for this > look right. -- This message was sent by Atlassian JIRA (v6.1#6144) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
