Mongo-Style Selectors
The simplest selectors are just a string or Mongo.ObjectID
. These selectors match the document with that value in its _id
field.
A slightly more complex form of selector is an object containing a set of keys that must match in a document:
// Matches all documents where deleted is false {deleted: false} // Matches all documents where the name and cognomen are as given {name: "Rhialto", cognomen: "the Marvelous"} // Matches every document {}
But they can also contain more complicated tests:
// Matches documents where age is greater than 18 {age: {$gt: 18}} // Also matches documents where tags is an array containing "popular" {tags: "popular"} // Matches documents where fruit is one of three possibilities {fruit: {$in: ["peach", "plum", "pear"]}}
