How to use hint in MongoDB?

// plain

Hints in MongoDB are used to provide the query optimizer with additional information about the query. This can help the query optimizer to choose the most efficient query plan.

Example

db.collection.find({name: "John"}).hint({name: 1})

This example will use the index on the name field to find documents with the name "John".

Code explanation

1. db.collection.find({name: "John"}) - This is the query that will be used to find documents with the name "John".
2. .hint({name: 1}) - This is the hint that will be used to provide the query optimizer with additional information about the query.
3. name: 1 - This is the index that will be used to find documents with the name "John".
