How can I perform a search in mongoose where a field (which is an array) contains something?

mongodb find mongoose

You want $all.

Here are a couple of examples from mongoose:https://github.com/LearnBoost/mongoose/blob/master/test/query.test.js#L396

On a side note, $where is typically not scalable.

mongodb find mongoose

MongoDB query syntax allows you to match an element array like that:

.find( { tags: 'tag1' } )

And, of course, it's working with Mongoose :)
