I am fairly new to Solr, so is possible I am writing the query wrong (I have Solr 4.10)
On this data: [{ "id": -1666, "otype": "ao", "parent_id": -1, "parent_type": "root", "name": "JOSHUA N AARON MD PA", "account_number": "002812300", "tax_id": "50042772325", "group_npi": 134630688333, "taxonomy": "364SP0808AAX", "start_date": "2001-04-01T00:00:00.00Z", "end_date": "2139-12-31T00:00:00.00Z", "_childDocuments_": [{ "otype": "p", "parent_id": -1666, "parent_type": "ao", "id": 271, "plan_id": "IBC", "plan_url_identifier": "ibc" }, { "otype": "a", "parent_id": -1666, "parent_type": "ao", "id": -88, "line1": "216 E PULASKI STE 235", "city": "Elkton", "state": "MD", "zip_code": "21921", "_childDocuments_": [{ "otype": "ph", "parent_id": -88, "parent_type": "a", "id": 1, "number": "5556201984" }, { "otype": "ph", "parent_id": -88, "parent_type": "a", "id": 2, "number":"5558696114" }] }, { "id": -1988, "otype": "ap", "parent_id": -1666, "parent_type": "ao", "plan_provider_id": "00283621227", "is_pcp": false, "is_specialist": false, "start_date": "2001-04-01T00:00:00.00Z", "end_date": "2014-05-01T00:00:00.00Z", "_childDocuments_": [{ "id": -819, "otype": "pf", "parent_id": -1988, "parent_type": "ap", "npi": 139670334111, "_childDocuments_": [{ "otype": "n", "parent_id": -819, "parent_type": "pf", "id": 1, "prefix": "Dr.", "first": "Frank", "middle": "N", "last": "Aaron" }], "organization_name": "Frank N Aaron", "date_of_birth": "1963-03-18T00:00:00.00Z", "gender_code": "M", "is_individual": true }] }, { "id": -1987, "otype": "ap", "parent_id": -1666, "parent_type": "ao", "plan_provider_id": "00283621007", "is_pcp": false, "is_specialist": false, "start_date": "2001-04-01T00:00:00.00Z", "end_date": "2014-05-01T00:00:00.00Z", "_childDocuments_": [{ "id": -815, "otype": "pf", "parent_id": -1987, "parent_type": "ap", "npi": 139670335001, "_childDocuments_": [{ "otype": "n", "parent_id": -815, "parent_type": "pf", "id": 1, "prefix": "Dr.", "first": "Joshua", "middle": "N", "last": "Aaron" }], "organization_name": "Joshua N Aaron", "date_of_birth": "1963-03-18T00:00:00.00Z", "gender_code": "M", "is_individual": true }] }] }] This query: q=otype:pf&fl=*,[docid],[child parentFilter=otype:pf limit=500] returns different documents in the childocuments array for each doc in result, 2 oype:pf in total. But they have the same structure in the datasource. I expected each to have one child, the otype:n document, but each has a different set of children and both more than intended, why?
