Adding ignoreNoIndex parameter

Hi! I’m trying to add the ignoreNoIndex flag to our Algolia search implementation, but I’m not sure where it should be included. From the API documentation (Crawler: IgnoreNoIndex | Algolia) it should be added in via javascript, but I’m not exactly sure - we have a php implementation in Wordpress. Is that a flag I can set in the Algolia.com interface somewhere?

Thank you!
