This article describes an error message that can appear in the Find section of the Episerver CMS when accessing features like Best Bets and more.
The error is:
Your index does not support statistics
This issue occurs when the index being used is expired. Please confirm the index configured in the section of web.config below.
<episerver.find serviceUrl="url" defaultIndex="index"/>
A lot of times it is a demo or developer Find index that has been decommissioned. The solution is to test with a known working index.
