Last modified: March 05, 2020

The AlteryxGallery_Lucene MongoDB contains the indices for search within the Gallery part of your Server instance. This article covers the AlteryxGallery_Lucene MongoDB schema version 27, which corresponds to the 2020.1 (current) Server version. Servers using either embedded MongoDB or user-managed MongoDB use this schema.

As a Server admin, you might need to access the MongoDB schema for your Server instance for reporting and analysis. You can access the MongoDB schema using any compatible client. mongo Shell is a good tool for command-line access. MongoDB Compass is a good tool for GUI access. If you use MongoDB Atlas you can access the database documents via the Atlas web console.

 We do not support making direct edits to your MongoDB database. Doing so can cause unexpected results.
