Find document with array that contains a specific value

mongodb mongoose

As favouriteFoods is a simple array of strings, you can just query that field directly:

PersonModel.find({ favouriteFoods: "sushi" }, ...); // favouriteFoods contains "sushi"

But I'd also recommend making the string array explicit in your schema:

person = {    name : String,    favouriteFoods : [String]}

mongodb mongoose

There is no $contains operator in mongodb.

You can use the answer from JohnnyHK as that works. The closest analogy to contains that mongo has is $in, using this your query would look like:

PersonModel.find({ favouriteFoods: { "$in" : ["sushi"]} }, ...);

mongodb mongoose

I feel like $all would be more appropriate in this situation. If you are looking for person that is into sushi you do :

PersonModel.find({ favoriteFood : { $all : ["sushi"] }, ...})

As you might want to filter more your search, like so :

PersonModel.find({ favoriteFood : { $all : ["sushi", "bananas"] }, ...})
