Hi there
We would like to use the new driver for golang, and one of our needs is to have apply a default filter to a query before the actual find\etc functions are being used.
for instance if a developer would like to create some custom query, once the query is evaluated, the driver will add the default query (i.e. $and:[{email:“x”}, userQuery]) to it.
Is this something possible to do? or for this to happen we must use a wrapper code that enforces it?
Thanks 
Hello @Oded_Valtzer, welcome to the MongoDB Community forum.
You can create a View on a collection - and on this view you can apply other queries.
While creating the view is easy, it has some restrictions. The documentation I had linked has all the details, but from the definition:
- A MongoDB view is a queryable object whose contents are defined by an aggregation pipeline on other collections or views.
- MongoDB does not persist the view contents to disk. A view’s content is computed on-demand when a client queries the view.
- MongoDB can require clients to have permission to query the view.
- MongoDB does not support write operations against views.
