ElasticPress, a fast and flexible search and query engine for WordPress, enables WordPress to find or “query” relevant content extremely fast through a variety of highly customizable features. WordPress out-of-the-box struggles to analyze content relevancy and can be very slow. ElasticPress supercharges your WordPress website making for happier users and administrators. The plugin even contains features for popular plugins.

Here is a list of the amazing ElasticPress features included in the plugin:

Search: Instantly find the content you’re looking for. The first time.

Instant Results: A built for WordPress search experience that bypasses WordPress for optimal performance. Instant Results routes search queries through a dedicated API, separate from WordPress, returning results up to 10x faster than previous versions of ElasticPress.

WooCommerce: With ElasticPress, filtering WooCommerce product results is fast and easy. Your customers can find and buy exactly what they’re looking for, even if you have a large or complex product catalog.

Related Posts: ElasticPress understands data in real time, so it can instantly deliver engaging and precise related content with no impact on site performance.

Protected Content: Optionally index all of your content, including private and unpublished content, to speed up searches and queries in places like the administrative dashboard.
