Indexes improve the efficiency of database queries by allowing MongoDB to locate matching documents without scanning the entire collection.

Without an appropriate index, a query may perform a collection scan.

For example, our application frequently searches users by email.

An index on email can improve this lookup.

MongoDB supports several index types:

- Single-field indexes.
- Compound indexes.
- Multikey indexes.
- Text indexes.
- Geospatial indexes.
- TTL indexes.

The correct index depends on the query patterns used by the application.
