What you'll learn
Why offline relevance testing is a vital search tuning tool

How to get Vespa to return matching and scoring information
Vespa is a highly powerful and scalable AI search engine - but it can be complex. We'll show you how to get started.
How to hook up Vespa to Quepid for relevance testing
Quepid is a popular tool that provides a ‘search workbench’. We'll show how to hook it up to Vespa.

We'll show you how to get started using these tools.
