Sorting documents in one core based on a field in another core

[Mark Robinson]

Hi,

I have a requirement to sort records in one core/ collection based on a
field in
another core/collection.

Could some one please advise how it can be done in SOLR.

I have used !join to restrict documents in one core based on field values
in another core. Is there some way to sort like that?


Thanks!
Mark.
