Posted on by adriannuta
In this article we talk about how to upgrade from Sphinx. Manticore Search is a fork from Sphinx Search 2.3.

  • adding texts as string attributes even if they are not using for any kind of operation (filtering, grouping, sorting) or mandatory to be present in results
  • using deprecated settings 

Having a quick look on the configuration can show issues or potential issues, this is why we want to offer a gift to our growing community!

When uploading your configuration file, we recommend to remove any database credentials first.

We suggest also you give as many possible details about your setup: how big is the data you have, how typical queries look and what issues you experience.
