Hello all,

I have to query all the databases on one server for docs matching a query.

I do it with this query for example:

db:list() ! db: open(.)/entry[@about='abc']

This query never hits the available attribute index.

I could rewrite the query to something like 

db:list() ! attribute(., 'abc', 'about')/..

and in this case it takes advantage of the index of course. 

The problem is that I have to implement more queries which have much more generic predicate structures where I probably won't be able to use indexes explicitly.

Is there any possibility to rewrite this query in order to use the indexes implicitly?

Thanks,

Marco.
