At this point when I see the Algolia search box on a site, I know I won't get a full search experience it will be slightly crippled with a custom interface and a forced auto-complete with JS only interface support.
An example of this is vuejs.org vs developer.mozilla.org. With Mozilla dev site, I have 'mdn' as my search key (both Firefox and Chrome) and I can type "mdn grid-template-columns" and I get results. With vuejs.org and Algolia, I have to go through multiple clicks and visual hunt and peck to find what I am looking for. It's a productivity killer.
