Running No SQL queries on a collection


In the previous recipe we described several techniques, including the one about searching the models in a collection with the where() method.

There are more advanced ways of searching the models in a collection, which can be done with the help of a Backbone extension named Backbone Query. It allows running No SQL (such as MongoDB) queries for searching, sorting, and paging the models in a collection.

Getting ready

You can download the Backbone Query extension from its GitHub page by going to https://github.com/davidgtonge/backbone_query. To include this extension into your project, save the backbone-query.js file into the lib folder and include the reference to it in index.html.

Note

Including the Backbone extension into your project is described in detail in the Extending an application with plugins recipe in Chapter 1, Understanding Backbone.
