Improve wordpress search performance/accuracy and enable faceted search by leveraging an ElasticSearch server.

This plugin is NOT a simple drop-in, it is expected you have some understanding of what an ElasticSearch server is and how it works. The goals/features of this plugin are:

• Replace default wordpress search functionality with that of an ElasticSearch server.
• Ability to specify what data points should be indexed and what the relevancy of those points are.
• Fall back to default wordpress search if ElasticSearch server is not responsive.
• Update ElasticSearch server when posts are removed/added/unpublished.
• Provide a faceting API for building your own custom searches

API/filter/faceting documentation can be found on the wiki:
