mongoose query same field with different values

Question

Is there a way to user mongoose.find({title:'some title'}) to query the same field with multiple values? For example something like this mongoose.find({title:'some title', title:'some other title'}) sends back only documents matching title:'some other title is there a way to accomplish this ?

Answer 1

You should use the MongoDB $in operator -

mongoose.find({title: {$in: ['some title', 'some other title']}})

You provide an array to $in operator and it will return all the documents which have an exact title in the array specified.

Answer 2

Found this in 2021 with the same question. It seems the $in operator is no longer necessary. As long as you pass find() an array of items, it will search for all of them.

Ex:

Furniture.find({
  room: [ 'first_id', 'second_id' ]
})

This will return the documents where room is the first OR second id.

Can be written in a query string like:

?room=first_id&room=second_id

There's no parsing needed—Node parses this into an array automatically.
