What you’ll learn
This advanced course covers RediSearch, the in-memory search engine built as a Redis Module. The course begins with a deep dive into the fundamentals of search engines. We then cover the structures and operations of RediSearch.
We’ll focus extensively on the RediSearch query language. We’ll look at the ins and outs of schema creation and document ingestion. You’ll also learn about the built-in aggregations engine: we’ll introduce the aggregation pipeline system and go over grouping and reducing, sorting, and the transformation syntax.
Finally, we’ll round out the course with an overview of synonyms and suggestions.
What you’ll build
This course will center around a real-time building permit search tool. In this way, you’ll learn how to use the many features of RediSearch to index and query a real-world data set.
The course will be presented in a language-agnostic fashion, with most exercises using the interactive Redis CLI.
