--\u003e\n\n\n\u003c!-- DESCRIPTION/ --\u003e\n\nQuery-Engine is a NoSQL and MongoDb compliant query engine. It can run on the server-side with Node.js, or on the client-side within web browsers\n\n\u003c!-- /DESCRIPTION --\u003e\n\n\nQueryEngine provides extensive Querying, Filtering, and Searching abilities for [Backbone.js Collections](http://documentcloud.github.com/backbone/#Collection) as well as JavaScript arrays and objects. The Backbone.js and Underscore dependencies are optional.\n\n\n## Features\n\n* runs on [node.js](http://nodejs.org/) and in the browser\n* supports [NoSQL](http://www.mongodb.org/display/DOCS/Advanced+Queries) queries (like [MongoDB](http://www.mongodb.org/))\n* supports filters (applying a filter function to a collection)\n* supports search strings (useful for turning search input fields into useful queries)\n* supports pills for search strings (e.g. `author:ben priority:important`)\n* supports optional live collections (when a model is changed, added or removed, it can automatically be tested against the collections queries, filters, and search string, if it fails, remove it from the collection)\n* supports parent and child collections (when a parent collection has a model removed, it is removed from the child collection too, when a parent collection has a model added or changed, it is retested against the child collection)\n* actively maintained, supported, and implemented by several companies\n\n\n## Compatability\n\nTested and working against:\n\n- No library\n- [Backbone](http://backbonejs.org) v0.9.2, v0.9.9, v1.0.0, v1.1.0, v1.1.2\n- [Exoskeleton](http://exosjs.com/) v0.5.1, v0.7.0\n\n\n## Using\n\n- [Interactive Demos](http://bevry.github.io/query-engine/)\n- [Complete Documentation](https://learn.bevry.me/queryengine/guide)\n\n\n\u003c!-- INSTALL/ --\u003e\n\n## Install\n\n### [NPM](http://npmjs.org/)\n- Use: `require('query-engine')`\n- Install: `npm install --save query-engine`\n\n### [Browserify](http://browserify.org/)\n- Use: `require('query-engine')`\n- Install: `npm install --save query-engine`\n- CDN URL: `//wzrd.in/bundle/query-engine@1.5.7`\n\n### [Ender](http://ender.jit.su/)\n- Use: `require('query-engine')`\n- Install: `ender add query-engine`\n\n\u003c!-- /INSTALL --\u003e\n\n\n### Direct\n- Use: `window.queryEngine` or `window.QueryEngine` whichever you prefer\n- CDN URL: `//bevry.github.io/query-engine/lib/query-engine.js`\n\n\n\u003c!-- HISTORY/ --\u003e\n\n## History\n[Discover the change history by heading on over to the `HISTORY.md` file.](https://github.com/bevry/query-engine/blob/master/HISTORY.md#files)\n\n\u003c!-- /HISTORY --\u003e\n\n\n\u003c!-- CONTRIBUTE/ --\u003e\n\n## Contribute\n\n[Discover how you can contribute by heading on over to the `CONTRIBUTING.md` file.](https://github.com/bevry/query-engine/blob/master/CONTRIBUTING.md#files)\n\n\u003c!-- /CONTRIBUTE --\u003e\n\n\n\u003c!-- BACKERS/ --\u003e\n\n## Backers\n\n### Maintainers\n\nThese amazing people are maintaining this project:\n\n- Benjamin Lupton \u003cb@lupton.cc\u003e (https://github.com/balupton)\n\n### Sponsors\n\nThese amazing people have contributed finances to this project:\n\n- BugHerd \u003csupport@bugherd.com\u003e (http://bugherd.com/)\n\nBecome a sponsor!\n\n[![Gratipay donate button](https://img.shields.io/gratipay/bevry.svg)](https://www.gratipay.com/bevry/ \"Donate weekly to this project using Gratipay\")\n[![Flattr donate button](https://img.shields.io/badge/flattr-donate-yellow.svg)](http://flattr.com/thing/344188/balupton-on-Flattr \"Donate monthly to this project using Flattr\")\n[![PayPayl donate button](https://img.shields.io/badge/paypal-donate-yellow.svg)](https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick\u0026hosted_button_id=QB8GQPZAH84N6 \"Donate once-off to this project using Paypal\")\n[![BitCoin donate button](https://img.shields.io/badge/bitcoin-donate-yellow.svg)](https://coinbase.com/checkouts/9ef59f5479eec1d97d63382c9ebcb93a \"Donate once-off to this project using BitCoin\")\n[![Wishlist browse button](https://img.shields.io/badge/wishlist-donate-yellow.svg)](http://amzn.com/w/2F8TXKSNAFG4V \"Buy an item on our wishlist for us\")\n\n### Contributors\n\nThese amazing people have contributed code to this project:\n\n- [Andrew Shults](https://github.com/andrewjshults) \u003candrewjshults@gmail.com\u003e — [view contributions](https://github.com/bevry/query-engine/commits?author=andrewjshults)\n- [Benjamin Lupton](https://github.com/balupton) \u003cb@lupton.cc\u003e — [view contributions](https://github.com/bevry/query-engine/commits?author=balupton)\n- [Farid Neshat](https://github.com/alFReD-NSH) \u003cFaridN_SOAD@yahoo.com\u003e — [view contributions](https://github.com/bevry/query-engine/commits?author=alFReD-NSH)\n- [Khalid Jebbari](https://github.com/DjebbZ) \u003chttps://github.com/DjebbZ\u003e — [view contributions](https://github.com/bevry/query-engine/commits?author=DjebbZ)\n- [Nicholas Firth-McCoy](https://github.com/nfm) — [view contributions](https://github.com/bevry/query-engine/commits?author=nfm)\n\n[Become a contributor!](https://github.com/bevry/query-engine/blob/master/CONTRIBUTING.md#files)\n\n\u003c!-- /BACKERS --\u003e\n\n\n\u003c!-- LICENSE/ --\u003e\n\n## License\n\nLicensed under the incredibly [permissive](http://en.wikipedia.org/wiki/Permissive_free_software_licence) [MIT license](http://creativecommons.org/licenses/MIT/)\n\nCopyright \u0026copy;
