Hoss Man created SOLR-11854: ------------------------------- Summary: multiValued PrimitiveFieldType should implicitly sort on min/max based on the asc/desc keyword Key: SOLR-11854 URL: https://issues.apache.org/jira/browse/SOLR-11854 Project: Solr Issue Type: Improvement Security Level: Public (Default Security Level. Issues are Public) Environment: Back in SOLR-2522, I added new syntax for (numeric) fields such that the {{field(someMultivaluedFieldName,min|max)}} syntax could be used to select either the min or max value of a multivalued (docvalues) field for use in other functions -- or for sorting.
A little while back, it occured to me that a good "default" behavior for all primative multivalued fields would be: * automatically use the "min" value when {{sort=someMultivaluedFieldName asc}} is attempted * automatically use the "max" value when {{sort=someMultivaluedFieldName desc}} is attempted These defaults seem like they would be a big improvement over the current "throw an error" default behavior -- especially since it naturally reduces down in the trivial case where all docs have at most 1 value anyway -- and would align in practice with how most people I've talked to seem to think "sorting on a multivalued field" should work in theory. If users don't like these dafaults, they can always use the explicit {{field(foo,min|max)}} syntax instead (ex: if users always want multivalued fields to sort on the 'min' value, regardless of the asc|desc selector) I've been experimenting with this off and on for a while, working up a POC patch -- I think it's worth doing (details to follow in comment) Reporter: Hoss Man Assignee: Hoss Man -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
