mongodb compass filter query

Question

In mongoDB compass I am getting no result with the below filters. Not sure what I am doing wrong.

1. {user: {uid: 'ttorone'}}
2. {user: {_id: ObjectId("5b9fc9567a1f050026a8bbda")}}

What I want is to filter out this document (where user-> uid is 'ttorone'). User is also an object here.

Answer 1

There is a syntax error you should try the following one instead:

{"user.uid" : "ttorone"}

 For example, in the COVID-19 database if you have to  records for all the person whose state id is 1(Delhi) so you have to put the below filter in the compass of Mongodb as:

{"state.id" : "1"}
