Abstract is a reading platform where visitors can access, read and download articles and book chapters from content published by Elsevier. The internal search feature within the website serves in the region of half a billion search requests annually.

Elasticsearch is a popular open-source search and analytics engine, and in 2019 Elsevier's Sciencedirect engineering team migrated the systems powering the website search to Elasticsearch. In this presentation we review the journey taken to move to Elasticsearch without compromising service to website visitors and at minimal commercial risk to Elsevier. The presentation touches on some of the Elasticsearch features adopted that help deliver a better search offering. In addition, the presentation reflects on the case for moving to Elasticsearch and its suitability for achieving present and future search objectives for the website.
