Add Enterprise Search user settingsedit

Change how Enterprise Search runs by providing your own user settings. User settings are appended to the ent-search.yml configuration file for your instance and provide custom configuration options.

Some settings that could break your cluster if set incorrectly are blacklisted. Review the list of settings that are generally safe in cloud environments. For detailed information about Enterprise Search settings, see the Enterprise Search documentation.

To add user settings:

  1. Log in to the Elasticsearch Service Console.

  2. Select your deployment on the home page in the Elasticsearch Service card or go to the deployments page.

    Narrow your deployments by name, ID, or choose from several other filters. To customize your view, use a combination of filters, or change the format from a grid to a list.

  3. From your deployment menu, go to the Edit page.
  4. In the Enterprise Search section, click Edit user settings. (For deployments with existing user settings, you may have to expand the Edit enterprise-search.yml caret instead.)
  5. Update the user settings.
  6. Click Save changes.

If a setting is not supported by Elasticsearch Service, an error message displays when you try to save your settings.
