All that the patch contributes is the infrastructure needed to allow multiple queries. It's structured so that the results from one query are available to construct the query for the next. The patch does not contribute a multi-query query parser, or means of merging the results into a final result.

I've got the patch (+tweaks) installed and working, and basic (i.e. non qt=multiquery) searches are working fine. What I can't figure out is how to enter in sequential queries from a browser client (i.e. 'query1', 'query2' etc.). Yep, understand you can't include proprietary code - but can you show the query syntax that will shove a couple of sequential queries into the requestHandler? Or am I misunderstanding the patch and there's server-side code to write?

I think you'd have to debug it all over again, and attach a new patch, to bring it up to date. Since this basically should work the same for a single query as does the current trunk, the first round of testing is just making sure everything still works as before. If you then change solrconfig.xml to specify multiple query processing chains, then obviously you need code that can work with that. I tested it with proprietary Nokia code, so I can't exactly include that. ;-) > Need infrastructure support in Solr for requests that perform multiple > sequential queries > ----------------------------------------------------------------------------------------- > > Key: SOLR-2026 > URL: https://issues.apache.org/jira/browse/SOLR-2026 > Project: Solr > Issue Type: New Feature > Components: SearchComponents - other > Reporter: Karl Wright > Priority: Minor > Fix For: 4.0 > > Attachments: SOLR-2026.patch, SOLR-2026.patch > > > Several known cases exist where multiple index searches need to be performed > in order to arrive at the final result.
