Alan Woodward resolved LUCENE-8597. ----------------------------------- Resolution: Fixed Fix Version/s: master (8.0) Thanks [~jim.ferenczi]! > Allow filtering of Intervals by their internal gaps > --------------------------------------------------- > > Key: LUCENE-8597 > URL: https://issues.apache.org/jira/browse/LUCENE-8597 > Project: Lucene - Core > Issue Type: Task > Reporter: Alan Woodward > Assignee: Alan Woodward > Priority: Major > Fix For: master (8.0) > > Attachments: LUCENE-8597.patch > > > We currently allow filtering of intervals by their total size, via the > `Intervals.maxwidth` static method. This works well enough, but there are > several cases where you might want to restrict the gap between two intervals, > but don't necessarily know the total width. For example, if you want to know > that an unordered pair `term1 term2` with no width restriction is less than > two positions away from another term: there is no current way to construct an > interval query that would return this. > To enable this, I propose adding a `gaps()` method to IntervalIterator, which > returns the number of internal gaps between the iterators constituent > sub-iterators. Terms and phrases, would return 0, and ordered/unordered > combinations would return the number of positions separating their immediate > children. Note that this does not include the gaps within any of those > children themselves. -- 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
