Elasticpath is a market leader for headless commerce microservices and are great partners. Search driven commerce has extreme value for online retailers. Search drives customers to better recommendations. It tracks the conversions and query terms that translate to more sales. With machine learning, search quantifies the search results that translate directly to sales.
For the last few weeks, we have worked closely with EP to build a search integration that brings the power of their platform to any search solution. We have more content coming soon describing that integration soon. For now you can find Handshake in the Elasticpath marketplace.
