Alan Woodward commented on LUCENE-8306: --------------------------------------- I've been playing around with various options for this API, and I think the one that fits best with highlighters is to add another method to Matches that returns a PostingsEnum across all term matches for a particular field. Highlighters can call {{Matches.getMatches(field)}} to get an iterator over intervals, which will allow them to decide how to build passages, and then {{Matches.getTermMatches(field)}} to get the individual term matches - this would also allow for exposing term frequencies for scoring, payloads, etc. I'm not sure yet whether or not to return a TermPostingsEnum or just a plain PostingsEnum - the latter keeps the API surface low, but the former could be useful for passage scoring. > Allow iteration over the term positions of a Match > -------------------------------------------------- > > Key: LUCENE-8306 > URL: https://issues.apache.org/jira/browse/LUCENE-8306 > Project: Lucene - Core > Issue Type: New Feature > Reporter: Alan Woodward > Assignee: Alan Woodward > Priority: Major > Attachments: LUCENE-8306.patch, LUCENE-8306.patch > > > For multi-term queries such as phrase queries, the matches API currently just > returns information about the span of the whole match.
