----------------------------------------------------------------
[~dsmiley], in a previous ticket (SOLR-10404) you changed how the fetch query
was being sent down to the following:
{code:java}
buf.append("{! df=").append(rightKey).append(" q.op=OR cache=false
}");//disable queryCache
{code}
I think we want this to be:
{code:java}
buf.append("{!lucene df=").append(rightKey).append(" q.op=OR cache=false
}");//disable queryCache
{code}
Otherwise if a defType is defined in the request handler that does not use "df"
or "q.op" those local params will be ignored.
I'm not sure if that is what's causing the problem in this case, but it does
appear like it would be a problem in general.

> Streaming expressions - fetch() does not work as expected
> ---------------------------------------------------------

> Key: SOLR-12505
> URL: https://issues.apache.org/jira/browse/SOLR-12505
> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Affects Versions: 7.3.1
> Environment: Windows 10, Java 10, Solr Cloud 7.3.1
> Reporter: Dariusz Wojtas
> Assignee: Joel Bernstein
> Priority: Major
> Attachments: names.zip
>
>
> The issue:
> # when I try to use fetch() within a streaming expression, it does not
> enrich the inner source data. The result is exactly the same as if there was
> no surrounding fetch() function.
> # but it works if I try to do a leftOuterJoin() function instead.
> Use the attached 'names' collection configuration.
> SOLR works in _cloud_ mode, streaming expressions do work, ie. stream(),
> join(), etc
