Subject [jira] Commented: (LUCENE-1823) QueryParser with new features for Lucene 3
Date Wed, 19 Aug 2009 00:12:14 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-1823?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12744792#action_12744792

Luis Alves commented on LUCENE-1823:
------------------------------------

{quote}
1. Operator precedence
{quote}
The new queryparser already supports this internally by disabling the GroupQueryNodeProcessor.
But we don't have any tescases and we need to add a simpler interface for the users by creating
a new Lucene3QueryParser class (with a diff name).

{quote}
2. Opaque terms
5. Complex phrases
{quote}
We should also implement number 5(Complex phrases) using number 2 (Opaque terms)

{quote}
8 Escaped wildcards
{quote}
LUCENE-1820 is also related to this.

> 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
