Query for documents where array size is greater than 1

Question

I have a MongoDB collection with documents in the following format:

{
  \"_id\" : ObjectId(\"4e8ae86d08101908e1000001\"),
  \"name\" : [\"Name\"],
  \"zipcod         


        

Answer 1

db.inventory.find( { dim_cm: { $elemMatch: { $gt: 22, $lt: 30 } } } )

you can use $gt and $lt in query.

Answer 2

You can use aggregate, too:

db.accommodations.aggregate(
[
     {$project: {_id:1, name:1, zipcode:1, 
                 size_of_name: {$size: "$name"}
                }
     },
     {$match: {"size_of_name": {$gt: 1}}}
])

// you add "size_of_name" to transit document and use it to filter the size of the name
