Get Existing Indexes for a Project


Groups and projects are synonymous terms. Your {GROUP-ID} is the same as your project id. For existing groups, your group/project id remains the same. This page uses the more familiar term group when referring to descriptions. The endpoint remains as stated in the document.

Retrieves the indexes that exist for all collections or specified collections on a specified host. Keys in indexes with multiple keys appear in the same order that they appear in the index. For more information, see Performance Advisor.
