Alan Woodward updated LUCENE-8645: ---------------------------------- Attachment: LUCENE-8645.patch > Add fixed field intervals > ------------------------- > > Key: LUCENE-8645 > URL: https://issues.apache.org/jira/browse/LUCENE-8645 > Project: Lucene - Core > Issue Type: Improvement > Reporter: Alan Woodward > Assignee: Alan Woodward > Priority: Major > Attachments: LUCENE-8645.patch > > > It can be useful to report intervals from one fields as if they came from > another. For example, fast prefix searches can be implemented by indexing > text into two fields, one with the full terms and one with edge-ngrams > enabled; to do proximity searches against terms and prefixes, you could wrap > a term query against the ngrammed field so that its intervals appear to come > from the normal field, and use it an an ordered or unordered interval. > This is analogous to the FieldMaskingSpanQuery, but has the advantage that we > don't use term statistics for scoring interval queries, so there is no issue > with mixing up field weights from different fields. -- 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
