Elastic App Search

Elastic App Search (built on top of the legendary Elasticsearch engine) is an incredibly powerful, deeply engineered leviathan that mathematically defines the "Developer-Centric Search" market. While Algolia abstracts the complexity, Elastic gives developers the raw, unadulterated power of the Elasticsearch core via a highly refined API. It is the absolute weapon of choice for hardcore software engineering teams who mathematically demand absolute architectural control over a massive index containing 500 million documents.
