Subject Re: Create a new ACTIVITY_FETCH from a transformation
Date Wed, 25 Jul 2018 22:35:11 GMT
The crawled URL is transmitted as part of the RepositoryDocument object to
the output connector.  If this is going to Solr, it's used as the
document's ID.  You can therefore customize Solr (or ElasticSearch) to
extract the data you need at the indexing end.

If this doesn't make any sense to you, then please be more specific about
what the disposition of each crawled document is.
