Reindexing Content Using Elasticsearch for CrafterCMS versions 3.1.18 and later

The steps listed below for reindexing content without disrupting service in production using Elasticsearch applies only to CrafterCMS versions 3.1.18 and later

Step 1: Content freeze

Once you are about to start a reindex you need to freeze your authoring/editing activity. If content is being updated in the live environment while you are rebuilding your indexes, you may miss updates. Ask the authors not to publish during your reindex process.

Step 2: Recreate Index

To simplify recreating an index of a site using Elasticsearch, CrafterCMS provides an API that recreates the underlying Elasticsearch index with the specified environment and site name.

http://localhost:9191/api/1/target/recreate/{env}/{site_name}

Simply call the API above with the required parameters to recreate your site index.

See here for more information on the API.

Step 3: Unfreeze Content

Now that reindexing is done, notify your authors that they may start editing and publishing activity.
