coronium.user.getUsers( ) -- search nested tables?

[Kevin Hincker]

I have user data that looks like this:

impressions: [ null, { expand: "y", invite: true,

}

],

When I use the dot syntax in the query fields of coronium.user.getUsers( ) like this:

coronium.user.getUsers( {impressions.expand="y"} ) I get a syntax error on the server. Mongo documents indicate that this would be the correct syntax for the search. Anyone have any thoughts? 

Thanks,

Kevin

UPDATE: Chris provided this code snippet, which does the trick - 

local answer = coronium.user.getUsers(

    {

        impressions = 

        { 

            ["$elemMatch"] = { expand = "y" } 

        }

    }

)
