Andrew Hankinson commented on SOLR-16847:
-----------------------------------------
Is it possible that this change has changed the behaviour of default parameters
when using the JSON Query API?
I have a list of default query fields (`qf`), but no default field (`df`) in my
/select request handler. My application talks with Solr over the JSON Query
API. Prior to upgrading to Solr 9.4.0, this worked fine. After updating I get
an error:
`Client exception => org.apache.solr.common.SolrException: no field name
specified in query and no default specified via 'df' param`
Queries in the Admin UI still work fine, but I believe this still uses the old
GET-based request handler. Trying a simple JSON query in the "Documents"
section of the admin UI produces this error for Solr 9.4, but works on Solr 9.3.

> Project: Solr
> Issue Type: Improvement
> Components: v2 API
> Reporter: Jason Gerlowski
> Assignee: Jason Gerlowski
> Priority: Major
> Labels: V2
> Fix For: main (10.0), 9.4

> Time Spent: 1h 40m
> Remaining Estimate: 0h

> Our v2 framework(s) still lack parity with our v1 RequestHandlers in one
> important area: configuration and initialization.
> v1 RequestHandlers have an {{init(NamedList)}} method which is called at
> creation time and allows RH's to handle any configuration attached to the
> relevant {{<requestHandler>}} tag in solrconfig.xml. This is most commonly
> used by administrators to override default values.
> We should add similar functionality to our JAX-RS framework. (It's also a
> gap in the homegrown annotation framework, but as we're moving away from this
> it's probably a much lower priority to add there).
