Yonik Seeley commented on SOLR-7672:
------------------------------------
Yeah, that probably works.
We can always just use some syntactic sugar if we don't want a literal \_root\_
mandated in whatever future query syntax we come up with.
Note to new readers: when you see italicized text, we normally don't mean it
that way... it's JIRA markup. Normally what we really mean is a literal
leading and trailing underscore on whatever is being proposed.
{code}_type_:_root_ is what is being proposed here.{code}
And if you see backslashes in front of the underscores, you're probably reading
the post in raw form (i.e. from an email) and it means that the author is just
trying to get JIRA to display literal underscores (but not backslashes).

> Project: Solr
> Issue Type: Improvement
> Components: query parsers, update
> Affects Versions: 5.2
> Reporter: Mikhail Khludnev
> Assignee: Mikhail Khludnev
> Fix For: 5.4, Trunk
>
>
> 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.
