Version 1.2

• Allow number of shards and replicas to be configurable.
• Improved searching algorithm. Favor exact matches over fuzzy matches.
• Query stack implementation to allow for query nesting.
• Filter and disable query integration on a per query basis.
• Support orderby parameter in WP_Query
• (Bug) We don't want to add the like_text query unless we have a non empty search string. This mimcs the behavior of MySQL or WP which will return everything if s is empty.
• (Bug) Change delete action to action_delete_post instead of action_trash_post
• (Bug) Remove _boost from mapping. _boost is deprecated by Elasticsearch.
• Improve unit testing for query ordering.
