I'm using Drupal 8 with Search API and Search API Solr Search.
I'm tasked with making an existing Solr installation searchable within Drupal. This core indexes PDFs and serves other systems, thus I may not edit the schema there. It can be assumed that this schema has fields like "author", "title" and "abstract".
I tried the following:
- Add a server in Search API: This seems to work as I see the (correct) number of indexed documents in Solr.
- Add an index with "Solr Document" as data source. I can see fields from the Solr core here.
However, in the View tab, I always see "0/0 Indexed".
Am I missing something here or is perhaps the wrong approach?
