HIGH PERFORMANCE SEARCH FOR JOOMLA!
Geek ElasticSearch is the most powerful, extremely fast, highly relevant and flexible search and filter system for your Joomla site. Our extension uses the Elasticsearch engine - a highly scalable open-source full-text search and analytics engine to index data and perform the search. Hence, it is possible to index, search, and analyze large volumes of data quickly and return search results in near real-time that other PHP-MySQL based search extensions can't do.
