Summary

In this chapter, we introduced the opportunity to use a pre-trained model called ELSER, which leverages vectors without users having to manage the vectorization process. It’s an out-of-the-box model that generates immediate value from a semantic search perspective. We applied ELSER to the challenge of phishing attacks with the task in mind being to limit the impact of such attacks. You should now be able to build your pipeline to load data in Elasticsearch and start building applications that leverage ELSER, whether in cybersecurity or beyond.

In the next chapter, we are going to go a step further in leveraging vectors by building a retrieval augmented generation application.
