 Re-indexing is done via CLI commands, as they are potentially long running, high memory usage tasks. To reindex a site, run:
 
 ```sh
-wp elasticpress index
+wp elasticpress sync
 ```
 
 **Note:** During the indexing process, the site will not use the Elasticsearch index for searches/queries, so some features like faceting or autosuggest will not work as expected until the process is finished.

 To re-sychronise the index and update mappings, run:
 
 ```sh

 ```
 
 To run across the entire network, use `xargs` with the above command. Given that the user index is a global one, it will be recreated for every single site. This is unnecessary, so you should only recreate this for one (the main) site. You'll also need to create the "network alias", which is a special index which allows cross-site searching.
 
 Overall, this would look like so:
 
 ```sh
-wp site list --field=url | xargs -I % wp elasticpress index --url=% --setup --indexables=post,term && wp elasticpress index --setup --indexables=user && wp elasticpress recreate-network-alias
+wp site list --field=url | xargs -I % wp elasticpress sync --url=% --setup --indexables=post,term --yes  && wp elasticpress sync --setup --indexables=user && wp elasticpress recreate-network-alias
 ```
 
 If you have enhanced search enabled for comments as well, you may want to add `comment` to `--indexables`.

 When using CLI to perform re-indexes, it's recommended to set the `--per-page` argument to a figure around `200`. By default, this figure is set to `350` which will often cause service timeouts. For example:
 
 ```sh
-wp site list --field=url | xargs -I % wp elasticpress index --url=% --per-page=200
+wp site list --field=url | xargs -I % wp elasticpress sync --url=% --per-page=200

 See `wp help elasticpress` for all available CLI commands.

+To ensure your [CLI Session doesn't time out](https://docs.altis-dxp.com/cloud/dashboard/cli/#session-timelimits), it is recommended to create a new `screen` session to run reindexing operations.
