Nesting decorators in streaming expressions

[Gintautas Sulskus]

Hi,

Is it possible to use decorator's output as a  data source for another
decorator?
My attempts to achieve this were throwing errors hence the question.

For instance, is it possible to have something like this?

gatherNodes(
    leftOuterJoin(
        leftOuterJoin(search(), search())
        leftOuterJoin(......)
    ),
    ...
)

Thanks,
Gin
