Hi,
I'm facing this weird error while running result grouping queries. This
started when I turned on "docvalues" for an existing facet field and
indexed the documents. Looking at the exception, I reverted back the change
and re-indexed the documents again. But I'm still getting the exception,
here's the stack trace.

Here's the current field definition :
<field name="MediaType" type="string" indexed="true" stored="true"
multiValued="true" required="false" omitNorms="true" />
I've re-indexed the documents, ran optimization on all four instances,
still I'm seeing the same error. I'm bit puzzled to figure out the
root cause. Do I need to delete the documents
tagged with MediaType and re-index ? I'm getting results back if I
don't use result grouping.
Any pointers will be appreciated.
- Thanks,
Shamik
