Chetan Mehrotra commented on OAK-3769:
--------------------------------------
Yes there are some benefits of exposing the broader syntax. But remember that
here you cannot specify the field (within fulltext phrase) as the field is
implicit as per the first parameter of contains call. So its somewhat limited.
Further per JCR spec only certain chars are allowed. Expecting the users to
handle escaping would not be good and its better to not leak the implementation
much. Boost has got into use, so has been allowed but extending that precendent
further we need to be careful. Oak supports the native query which can be used
by user if they want to rely on such implementation detail.
It would be preferable to go with a restrictive set and expose operators on a
case by case basis

> Running the below query, results in Exception pointed by [1]
> /jcr:root/content/dam//element(*,dam:Asset)[jcr:contains(jcr:content/metadata/@cq:tags,
> 'stockphotography:business/business_abstract')] order by @jcr:created
> descending
> Also if you remove the node at
> /oak:index/damAssetLucene/indexRules/dam:Asset/properties/cqTags and
> re-index the /oak:index/damAssetLucene index, the query works.
> Seems '/' is special character and needs to be escaped by Oak.
