In the world of AI-powered search, relevance is everything. Go beyond the limits of pure keyword or vector search in Blend Hybrid Search, an intermediate course for developers and ML engineers. You will learn to build a state-of-the-art search system by combining the precision of keyword matching (like BM25) with the semantic power of dense vectors. This course provides a complete, hands-on framework for optimizing search performance using open-source tools as our implementation example.
You won't just build a hybrid search function; you will master the art of tuning it. Through a project-driven approach, you will learn to systematically adjust weighting parameters and use the industry-standard NDCG metric to objectively measure and prove the impact of your changes. You will leave with a reusable evaluation script and a data-driven methodology for squeezing the maximum relevance from any search application.
In this module, you will learn the fundamental principles behind state‑of‑the‑art search and immediately put them into practice. You will build a complete hybrid search function from scratch by combining BM25 keyword scores with dense vector scores, and you will experiment with the alpha weighting parameter to understand how it affects ranking behavior. This module establishes the foundation for evaluation and tuning, which you will perform in the next module.

Coursera brings together a diverse network of subject matter experts who have demonstrated their expertise through professional industry experience or strong academic backgrounds. These instructors design and teach courses that make practical, career-relevant skills accessible to learners worldwide.
When will I have access to the lectures and assignments?
To access the course materials, assignments and to earn a Certificate, you will need to purchase the Certificate experience when you enroll in a course. You can try a Free Trial instead, or apply for Financial Aid. The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
What will I get if I subscribe to this Specialization?
When you enroll in the course, you get access to all of the courses in the Specialization, and you earn a certificate when you complete the work. Your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile.
Is financial aid available?
Yes. In select learning programs, you can apply for financial aid or a scholarship if you can’t afford the enrollment fee. If fin aid or scholarship is available for your learning program selection, you’ll find a link to apply on the description page.
