Christine Poerschke commented on SOLR-5730: ------------------------------------------- bq. ... i'm not really a fan of the 2 new disjoint top level config options ... I agree that having a {{<useSortingMergePolicy>true</useSortingMergePolicy>}} element in solrconfig.xml and a {{<mergeSortSpec>timestamp desc</mergeSortSpec>}} element in schema.xml is tricky but personally am not won over by either of the obvious two alternatives either: *Alternative #1 solrconfig.xml element only:* + advantage: the element is co-located with the existing <mergePolicy> element \- disadvantages: * solrconfig.xml references schema.xml field names * solr.search.SolrIndexSearcher would need (more) access to the solr.update.SolrIndexConfig object \[implementation detail: SolrIndexSearcher.buildAndRunCollectorChain needs to be able to pass the merge policy sort to EarlyTerminatingSortingCollector but only one of the two SolrIndexSearcher constructors currently takes an SolrIndexConfig argument.\] *Alternative #2 schema.xml element only:* + advantage: the element uses solr field names defined in the same file \- disadvantage: the presence or absence of an element in schema.xml has a side effect on how the solrconfig.xml <mergePolicy> element is instantiated *Alternative #3 perhaps there is another way?* > make Lucene's SortingMergePolicy and EarlyTerminatingSortingCollector > configurable in Solr > ------------------------------------------------------------------------------------------ > > Key: SOLR-5730 > URL: https://issues.apache.org/jira/browse/SOLR-5730 > Project: Solr > Issue Type: New Feature > Reporter: Christine Poerschke > Assignee: Christine Poerschke > Priority: Minor > Attachments: SOLR-5730-part1of2.patch, SOLR-5730-part2of2.patch > > > *Example configuration (SortingMergePolicy):* > solrconfig.xml > {noformat} > <useSortingMergePolicy>true</useSortingMergePolicy> > {noformat} > schema.xml > {noformat} > <mergeSortSpec>timestamp desc</mergeSortSpec> > {noformat} > *Example use (EarlyTerminatingSortingCollector):* > {noformat} > &sort=timestamp+desc&segmentTerminateEarly=true > {noformat} -- 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
