ElasticSearch Backbone library for quickly building Faceted Search front ends.

es-backbone.js

ElasticSearch Backbone/Mustache library for quickly building Faceted Search front ends.

Overview

If your data is already indexed and you know a bit about the ElasticSearch API, then this library should allow you to build an interactive front end for doing faceted search. I've built three so far, and the last one took 35 minutes to build, debug, and deploy.

It also uses flot to provide pretty interactive graphs as inspired by Shay's post here: http://www.elasticsearch.org/2011/05/13/data-visualization-with-elasticsearch-and-protovis/

See examples/simple/simple.php for all the library dependencies. Those paths are probably not the best places to serve them from.

Where to Start

In the examples directory is a simple example (but it has no server to work with). To get it working grep through the files or "TODO" and "OPTIONAL" to figure out what you need to do.

If you have a public ES endpoint I'd love to have a working example to show off in this repository.

• added esbbSearchFilterTermsSelectorView to have one text entry field per filter rather than a single box for all filters
• added pushstate support to modify URL in address bar
• Timeline View can be displayed with the bars shown horizontally so it can fit in the sidebar

0.1 Initial Release. Works for me. ;)
