Finding documents in mongodb collection where a field is equal to given integer value

Question

I would like to find all documents where the field property_id is equal to -549. I tried:

db.getCollection('CollectionName').find({'property_id' : -549 })

This returns no records with a message: "Fetched 0 record(s)."

But I am seeing the document right there where the field property_id is -549. I am not sure what I am doing wrong. The type of field is int32.

Answer 1

Check if there is a space in the field name 'property_id': Try

db.getCollection('CollectionName').find({'\uFEFFproperty_id' : -549 })
