I know the doc ids from one core have nothing to do with the other. I was going to use the docId returned from the first core in the solr results and store it in the second core that way the second core knows about the doc ids from the first core. So when you query the second core from the Filter in the first core you get returned a set of data that includes the docId from the first core that the document relates to.
I have backed off from this approach and have a user defined primary key in the firstCore, which is stored as the reference in the secondCore and when the filter performs the search it goes off and queries the firstCore for each primary key and gets the lucene docId from the returned doc.

So anything that uses doc IDs from one Solr instance to create a filter on another instance doesn't seem to be something you'd want to do... Which may just mean I don't understand what you're trying to do. Can you back up a bit and describe the higher-level problem? This seems like it may be an XY problem, see: http://people.apache.org/~hossman/#xyproblem Best Erick On Tue, Nov 30, 2010 at 6:57 AM, Lohrenz, Steven <steven.lohr...@hmhpub.com>wrote: > Hi, > > I was wondering how I would go about getting the lucene docid included in > the results from a solr query? > > I've built a QueryParser to query another solr instance and and join the > results of the two instances through the use of a Filter.
