Why Discovery exists
The Omneo API list endpoints are built for precise, filtered retrieval of records you can already describe. Discovery is built for the opposite: a person typing a partial name into a box and expecting ranked matches back in milliseconds.
Discovery is read-only. Every write still goes through the Omneo API, and Discovery reflects the result.
Indexes
An index is a named collection of documents that can be searched as a unit, for exampleprofiles or products. Each index has a primary key, a set of searchable attributes, and a smaller set of attributes that can be filtered and sorted on.
Additional indexes such as locations and product lists can be configured, and the attributes written into any index can be customised. Both are set up by Omneo during provisioning.
