Alexandre Rafalovitch closed SOLR-2026. --------------------------------------- Resolution: Information Provided Fix Version/s: (was: 6.0) (was: 4.9) > 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 > 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. Typically, these have the constraint > that the results from one search query are required in order to form a > subsequent search query. While it is possible to write a custom > QueryComponent or search handler to perform this task, an extension to the > SearchHandler base class would readily permit such query sequences to be > configured using solrconfig.xml. > I will be therefore writing and attaching a patch tomorrow morning which > supports this extended functionality in a backwards-compatible manner. The > tricky part, which is figuring out how to funnel the output of the previous > search result into the next query, can be readily achieved by use of the > SolrRequestObject.getContext() functionality. The stipulation will therefore > be that the SolrRequestObject's lifetime will be that of the entire request, > which makes complete sense. (The SolrResponseObject's lifetime will, on the > other hand, be limited to a single query, and the last response so formed > will be what gets actually returned by SearchHandler.) -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
