--------------------------------------

             Summary: introduce implicit _parent_:true  
                 Key: SOLR-7672
                 URL: https://issues.apache.org/jira/browse/SOLR-7672
             Project: Solr
          Issue Type: Improvement
          Components: query parsers, update
    Affects Versions: 5.2
            Reporter: Mikhail Khludnev
             Fix For: 5.3


Solr provides block join support in non-invasive manner. It turns out, it gives a chance to shoot a leg. As it was advised by [~thetaphi] at SOLR-7606, let AddUpdateCommand add _parent_:true field to the document (not to children). Do it *always* no matter whether it has children or not.    
Also, introduce default values for for block join qparsers \{!parent *which=\_parent\_:true*} \{!child *of=\_parent\_:true*} (sometimes, I rather want to hide them from the user, because they are misunderstood quite often).  
Please share your concerns and vote.
