The Search Crawler still requires Kerberos authentication but PI Web API 2016 introduced the option to install a Shared Index Search. Please see Shared Indexes in a PI Web API cluster. Our public PI Web API endpoint is set up with a Shared Search and hence allows you to query the search index even security is configured for Basic authentication.
Please see Indexed Search Shared Index CTP White Paper for additional details. Please note that the Shared Search is still a CTP.
