backbone_query - MongoDB-like query interface to Backbone collections

Nice JavaScript add-on for Backbone from Dave Tonge that provides a MongoDB-like query API for your collections:

MyCollection.query({
  // Models must match all these queries
  $and:{
    title: {$like: "news"}, // Title attribute contains the string "news"
    likes: {$gt: 10}}, // Likes attribute is greater than 10

  // Models must match one of these queries
  $or:{
    featured: true, // Featured attribute is true
    category:{$in:["code","programming","javascript"]}}
    //Category attribute is either "code", "programming", or "javascript"
});
