ASF subversion and git services commented on LUCENE-8477: --------------------------------------------------------- Commit e460356abeb1bd075a885d905a1d0873469bbd43 in lucene-solr's branch refs/heads/branch_8x from Jim Ferenczi [ https://gitbox.apache.org/repos/asf?p=lucene-solr.git;h=e460356 ] LUCENE-8477: Restore public ctr for FilteredIntervalsSource > Improve handling of inner disjunctions in intervals > --------------------------------------------------- > > Key: LUCENE-8477 > URL: https://issues.apache.org/jira/browse/LUCENE-8477 > Project: Lucene - Core > Issue Type: New Feature > Reporter: Alan Woodward > Assignee: Alan Woodward > Priority: Major > Fix For: 8.1 > > Attachments: LUCENE-8477.patch, LUCENE-8477.patch, LUCENE-8477.patch, > LUCENE-8477.patch > > Time Spent: 20m > Remaining Estimate: 0h > > The current implementation of the disjunction interval produced by > {{Intervals.or}} is a direct implementation of the OR operator from the Vigna > paper. This produces minimal intervals, meaning that (a) is preferred over > (a b), and (b) also over (a b). This has advantages when it comes to > counting intervals for scoring, but also has drawbacks when it comes to > matching. For example, a phrase query for ((a OR (a b)) BLOCK (c)) will not > match the document (a b c), because (a) will be preferred over (a b), and (a > c) does not match. > This ticket is to discuss the best way of dealing with disjunctions. -- 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
