How to make search works for 3 indices on algolia side ?

I added algolia support on laravel 10 site and made importing of 3 table tasks, users, categories

Search works for any of these 3 indices. But how can I search which works for all these 3 indices on fields :

tasks.name, tasks.description, users.name, categories.name ?

Can I make such search on algolia side with 3 tables ?

If yes, in which way ?

    "php": "^8.2",
    "algolia/algoliasearch-client-php": "^3.4",
    "laravel/framework": "^10.34.2",
    "laravel/scout": "^10.6",

Thanks in advance!
