What is an operation?
An operation is any process that communicates with the Search.io engine.
Operations are incurred when:
a search request is made
when search suggestions are fetched
when new content is added, deleted or updated to your collection
when a search result is interacted with and that interaction is recorded
schema or pipeline is viewed, added, updated, or deleted from a collection
You can always keep track of your operations in the Usage section of your Console.
