pay only for indexed

If you're using a search engine or database, you might notice you're paying for data storage you never use. With a pay-only-for-indexed model, you're charged based on the information that's actually searchable and organized. This means if you have lots of raw files sitting there that aren't tagged or indexed, you won't be billed for them. It keeps costs predictable and directly tied to what you actively use.
