[jira] [Commented] (VXQUERY-208) Lucene Index Filter for Values

["Till Westmann (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/VXQUERY-208?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15305070#comment-15305070 ] 

Till Westmann commented on VXQUERY-208:
---------------------------------------

Shouldn't we first look at filters for string containment or equality? 
Numeric predicates are probably not Lucene's sweet spot.

> Currently the Lucene filters for child path steps. Extend this option to include filters for specified values.
> Example index query:
> for $x in collection-from-index('data/books', '/bookstore/book/price', '>40')
> return $x;
> Example non-indexed:
> for $x in collection('data/books')/bookstore/book/price
> where $x>40
> return $x;
