Re: Solr (5.3.1) doesn't delete orphaned child documents

[Alexandre Rafalovitch]

I suspect not (starting from 'delete parent only'). I would check this
against Solr 5.5 as it fixed a bunch of parent/child related issues.
See, for example, SOLR-5211

Solr (5.3.1) doesn't delete orphaned child documents

[naeem.tahir]

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
