Index profiles allow your applications to send documents for indexing to a consistent endpoint (the profile alias) and change the backend index pipeline as needed. The profile is also a simple way to use one pipeline for multiple collections without any one collection "owning" the pipeline.
Associating a profile with a pipeline is simply a mapping, and the profile is considered an alias for the pipeline. The mapping can be managed in the UI or with the Index Profiles API.
The Profiles tab shows the index profiles on the left and the query profiles on the right. Hover over the name of a profile, and an edit button will appear to allow you to change the pipeline the profile is mapped to. Hover over the name of a pipeline, and you will be able to jump to edit that pipeline.
Click Add Profile to add a profile. The next screen will show a form allowing you to define the profile name and either select an existing pipeline or create a new pipeline with the name you choose. Click Create to save the new profile.
