Improving order history search using semantic search with Amazon OpenSearch Service

If you’ve ever shopped on Amazon, you’ve used Your Orders. This feature maintains your complete order history dating back to 1995, so you can track and manage every purchase you’ve made. The order history search feature lets you find your past purchases by entering keywords in the search bar. Beyond just finding items, it provides a straightforward way to repurchase the same or similar items, saving you time and effort. In this post, we show you how the Your Orders team improved order history search by introducing semantic search capabilities on top of our existing lexical search system, using Amazon OpenSearch Service and Amazon SageMaker.
