Hi, I noticed some strange behavior when deleting orphaned child documents in Solr 5.3.1. I am indexing nested documents in parent/child hierarchy. When I delete a child document whose parent is already deleted previously, child document still shows up in search. I am using deleteById() that always returns with a success code. Here is an illustration:
A parent P has n (=3) children, say a, b, and c. (P) |-(a) |-(b) |-(c) i) Index all four documents with P as parent and a,b,c as children of P. ii) Search returns 4 documents (P, a, b, c). iii) Delete P. iv) Search returns 3 documents (a, b, c) v) Now delete 'a' vi) Search still returns 3 documents including 'a'. Same behavior when you delete 'b' and 'c' as well. Can someone comment if this is the expected behavior? Thanks & regards, Naeem
