> After upgrading from 4.5.1 to 4.7+, a schema including a {{"*"}} dynamic field as text gets a cast exception when using a sort function and result grouping.
> Repro (with example config):
> # Add {{"*"}} dynamic field as a {{TextField}}, eg:
> {noformat}
> <dynamicField name="*" type="text_general" multiValued="true" />
> {noformat}
> # Create sharded collection
> {noformat}
> curl 'http://localhost:8983/solr/admin/collections?action=CREATE&name=test&numShards=2&maxShardsPerNode=2'
> {noformat}
> # Add example docs (query must have some results)
> # Submit query which sorts on a function result and uses result grouping:
> {noformat}

> It looks like {{serializeSearchGroup}} is matching the sort expression as the {{"*"}} dynamic field, which is a TextField in the repro.
