Adrien Grand created LUCENE-8708: ------------------------------------ Summary: Can we simplify conjunctions of range queries automatically? Key: LUCENE-8708 URL: https://issues.apache.org/jira/browse/LUCENE-8708 Project: Lucene - Core Issue Type: Improvement Reporter: Adrien Grand
BooleanQuery#rewrite already has some logic to make queries more efficient, such as deduplicating filters or rewriting boolean queries that wrap a single positive clause to that clause. It would be nice to also simplify conjunctions of range queries, so that eg. {{foo: [5 TO *] AND foo:[* TO 20]}} would be rewritten to {{foo:[5 TO 20]}}. When constructing queries manually or via the classic query parser, it feels unnecessary as this is something that the user can fix easily. However if you want to implement a query parser that only allows specifying one bound at once, such as Gmail ({{after:2018-12-31}} https://support.google.com/mail/answer/7190?hl=en) or GitHub ({{updated:>=2018-12-31}} https://help.github.com/en/articles/searching-issues-and-pull-requests#search-by-when-an-issue-or-pull-request-was-created-or-last-updated) then you might end up with inefficient queries if the end user specifies both an upper and a lower bound. It would be nice if we optimized those automatically. -- 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
