Compass thinks a query using $expr and $or (probably other logical operations as well) is not proper syntax.

A query like:

{ $expr: { $or: [ true, true ] } }

should be valid, but isn't, though the following does work:

{ $expr: { $in: [ true, true ] } }

How about adding a checkbox to Compass along the lines of:

"Yeah I know you think the query syntax is incorrect, but execute the @#%$ing query anyway"

....so that when we run into valid queries that Compass doesn't understand, we can still make progress?
