1. Welcome! In this unit, you'll learn how to perform advanced queries in Atlas Search. My name is `instructor_name`. I'm a `instructor_role` at MongoDB, and I'll be your guide through this unit.
2. As you may have noticed, the Atlas Search query language is feature rich. A lot of our queries can be created using only a subset of those features. But sometimes, we need to fine-tune our search queries, whether that means searching multiple fields, excluding certain terms from our search, sorting our results in a particular order, or accounting for human errors like typos. In this unit, we'll show you some advanced Atlas Search features to help you accomplish all of this and more.
3. We'll begin by looking at the compound operator, along with the `must`, `mustNot`, `filter` and `should` clauses. The compound operator helps us narrow results or prioritize certain qualities over others.
4. Then, we'll build on this foundation by using the compound operator with multiple clauses and nested clauses. We'll share some common use cases and examples from our movie catalog app.
5. Next, we'll look at sorting in Atlas Search. By default, Atlas Search sorts by relevance score, which is usually what we want. But we can also customize the sorting behavior to further sequence the results.
6. Finally, we'll use the fuzzy search feature. Fuzzy search generates relevant results even when our search terms are misspelled.
7. By the end of this unit, you'll be able to write advanced search queries in Atlas Search to generate the results your users need from your data.
8. Let's get started!
