Tommaso Teofili commented on OAK-2234:
--------------------------------------
updated test and benchmarks in
https://gist.github.com/tteofili/52856d938fcd465eab58, it looks like using the
filter directly in the _IndexSearcher#search_ is a bit faster than using it to
create a _ConstantScoreQuery_.
> Support property existence query
> --------------------------------
>
> Key: OAK-2234
> URL: https://issues.apache.org/jira/browse/OAK-2234
> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: oak-lucene
> Reporter: Chetan Mehrotra
> Assignee: Chetan Mehrotra
> Priority: Minor
> Fix For: 1.0.9, 1.2
>
>
> Add support for property existence query like
> {noformat}
> select [jcr:path] from [nt:base] where propa is not null
> {noformat}
> Opposite of this cannot be be supported i.e. {{propa is null}} though!
> With OAK-1208 query creation logic explicitly ignores such queries but with
> recent Lucene changes it appears to be possible LUCENE-995
