Michael Gibney commented on SOLR-13094:
---------------------------------------
It looks like there may be other things going on here, but based on the
information included in the description, it's worth pointing out that there are
fundamental issues with distributed faceting over SortableTextField, described
in SOLR-13056. I realize that these issues may not be directly related to the
problem(s?) described/linked to here.
But for now it might be best to avoid distributed faceting over
SortableTextField (e.g., separate fields for sorting and searching/faceting),
and doing so might address your immediate issue.
