/api/v2/search/incremental
Is this API officially supported?
This API seems to be used for global search at Zendesk Support.
However I couldn't find the document about it.
If it's supported, I'd like to use it for my app to get exactly same result as searched from UI

Hey Yusuke,
This endpoint is not officially supported. I'd highly suggest using the search api instead.
Have a wonderful day!
