childFilter Solr 6.6

[Roopa Rao <ro...@gmail.com>]

Hi -
I am on version Solr 6.6 and using parent and child construct

Query as follows:
 [child parentFilter='field1:value1' childFilter='((field1:(value1)) AND
({!terms f=field2}value2))' limit=1]

Here I want to sort this children by field3 and return only the top 1
element (hence limit=1) . Is there a way to do this?

I notice that when the children are returned, it is being returned in the
order it was indexed. Is this guaranteed?
If it is going to return the order in which is indexed that will work in my
case too, as I index the field3 data in the order which it should be shown.

Thanks,
Roopa

Hi,
childFilter is guaranteed to return the documents in the order it was
provided to Solr.

If you want to sort or do other interesting things, consider [subQuery]
