In the first module, you'll learn about the basics of Elasticsearch, its purpose, features, and use cases. You'll also be guided on how to install and configure Elasticsearch and understand its distributed architecture.

The second module delves into optimizing search-based queries in Elasticsearch. Topics include using Elasticsearch's Explain API, improving query performance techniques, and understanding Elasticsearch's scoring algorithm.

This module introduces learners to advanced query mechanisms, including Boolean, fuzzy, and proximity queries. They'll also explore nested queries, script queries, join queries, and the use of Elasticsearch's search templates.

Learners will get practical experience, including installing Elasticsearch on their machines, creating indices, formulating various queries, optimizing search processes, and implementing advanced querying mechanisms.

The course takes approximately 12 hours to complete. This estimate includes time for lectures, hands-on exercises, and projects, but the actual time may vary depending on individual pace and understanding.

Absolutely, the course is designed for self-paced learning. This allows you to progress through the material at a pace that suits your individual needs and schedule.

Access to lectures and assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for free. To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the audit option:

• The course may not offer an audit option. 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.

When you purchase a Certificate you get access to all course materials, including graded assignments. Upon completing the course, your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile. If you only want to read and view the course content, you can audit the course for free.

You will be eligible for a full refund until two weeks after your payment date, or (for courses that have just launched) until two weeks after the first session of the course begins, whichever is later. You cannot receive a refund once you’ve earned a Course Certificate, even if you complete the course within the two-week refund period. See our full refund policy.
