Answer 1

Default sorting criteria in Solr is score desc, where score is a virtual field and it actually represents the document's score.
Once one is passing &sort=name asc it will override default sorting.

Possible solution here might be something like this: &sort=score desc, name asc. Which literally means: please sort by score first and for documents with equal score please make a tie-break by name ascending.

It should work as long as you will have equal scores for doc1, doc2, doc5, doc6.

If it is not the case - then check out this Solr Wiki link for more details how to penalize docs with inv:0.
