Use AND - operator in the find method

Question

I have a collection with the array field. If I want to find all documents with specific tag I use next query:

db.Bookmarks.find({tags : {$regex: \"bbb\"}})
         


        

Answer 1

You can use the $all query operator to do this:

db.Bookmarks.find({tags: {$all: ['bbb', 'ccc']}})

You can use regular expressions as well. To include tags that start with c instead:

db.Bookmarks.find({tags: {$all: ['bbb', /^c/]}})
