How to query elements in an array in MongoDB

[irunika]

Let's say that we have an array looks like as follows

{ 
  id: 'someId',
  myArray: [
     'element1',
     'element2'
  ]
}

I want to find out all the documents where 'element1' is present in myArray.

If we run it in MongoDB it looks like
db.myCollection.find( { myArray: { $in: ['element1'] } } )
According to https://docs.mongodb.com/manual/reference/operator/query/in/.

I was trying to construct this query with the operator available in the documentation https://loopback.io/doc/en/lb4/Where-filter.html but could not find an answer. There are operators called inq and nin but they not supported with array of elements.

Is there a way to do it in LB4. This is one of the most widely used operations in MongoDB and I might have missed it.

Thanks in advance!
