Has anyone done further work on Algolia search with Kirby 3? The code @nigel posted above is not working for me. It looks like recent changes to the Search plugin on getkirby.com are incompatible with this code. Just wondering if anyone else has made the updates before I go digging through the plugin to fix it.
According to the error message, the error is caused in this line in the $collection->filterBy() method: -v2/kirby/blob/1505b659472480311aa166767c7a3652c3e766fe/vendor/getkirby/toolkit/lib/collection.php#L274
