Per:

[https://github.com/discourse/discourse/commit/06365023c4f215bb6867efe7e41bf740c919586b](https://github.com/discourse/discourse/commit/06365023c4f215bb6867efe7e41bf740c919586b)

If you are searching by email use:

```plaintext
SITENAME.com/admin/users/list/all.json?email=some@email.com

```

Using filter is inefficient and not recommended for this use case!
