NSX plugin ver 1.0.1 - query methods

I'm working with the version 1.0.1 of the NSX plugin for vRO and I can't find any method to query for objects.

For example, I was able to orchestrate the creation of 4 Logical Switches for a user. But in another workflow I need to find all Logical Switches which names includes the name of the user.

Is there any way to do this with the plugin or I need to use the HTTP-REST plugin?

(Same thing for other objects like Edges)

Thanks a lot,

D.
