Michael Busch commented on LUCENE-1823: --------------------------------------- Luis and Adriano, the QP config looks quite overwhelming with all the Attributes. I'm not sure if the AttributeSource/Attribute stuff is a good fit for this type of configuration. Couldn't we achieve the same with a Properties (Hashtable) approach and constants or something similar. This would be a good place to start to reduce the complexity of the new QP. > QueryParser with new features for Lucene 3 > ------------------------------------------ > > Key: LUCENE-1823 > URL: https://issues.apache.org/jira/browse/LUCENE-1823 > Project: Lucene - Java > Issue Type: New Feature > Components: QueryParser > Reporter: Michael Busch > Assignee: Luis Alves > Priority: Minor > Fix For: 3.1 > > Attachments: lucene_1823_any_opaque_precedence_fuzzybug_v2.patch, > lucene_1823_foo_bug_08_26_2009.patch > > > I'd like to have a new QueryParser implementation in Lucene 3.1, ideally > based on the new QP framework in contrib. It should share as much code as > possible with the current StandardQueryParser implementation for easy > maintainability. > Wish list (feel free to extend): > 1. *Operator precedence*: Support operator precedence for boolean operators > 2. *Opaque terms*: Ability to plugin an external parser for certain syntax > extensions, e.g. XML query terms > 3. *Improved RangeQuery syntax*: Use more intuitive <=, =, >= instead of [] > and {} > 4. *Support for trierange queries*: See LUCENE-1768 > 5. *Complex phrases*: See LUCENE-1486 > 6. *ANY operator*: E.g. (a b c d) ANY 3 should match if 3 of the 4 terms > occur in the same document > 7. *New syntax for Span queries*: I think the surround parser supports this? > 8. *Escaped wildcards*: See LUCENE-588 -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online. --------------------------------------------------------------------- To unsubscribe, e-mail: java-dev-unsubscr...@lucene.apache.org For additional commands, e-mail: java-dev-h...@lucene.apache.org
