You can modify the list of posts displayed in feed using pre_get_posts action. And to target only feeds, you can use is_feed conditional tag.

So such code can look like this:

add_action( 'pre_get_posts', function ( $query ) {
    if ( ! is_admin() && is_feed() && $query->is_main_query() ) {
        if ( isset($_GET['q']) && trim($_GET['q']) ) {
            $query->set( 's', trim($_GET['q']) );
        }
    }
} );

This way you can go to example/feed/?q=KEYWORD and you'll get filtered feed (be careful - most browsers are caching feeds, so you'll have to force them to refresh it).

Here's how we can use the builtin public query parameters on feeds:

Query parameter: s

We can use the s query parameter on the feed:

https://example/feed/?s=KEYWORD

This will generate a feed for the keyword on all searchable post types.

Query parameter: post_type

We can restrict it to a given post type with:

https://example/feed/?s=KEYWORD&post_type=post

Query parameter: exact

We can also use the exact query search parameter to exactly match the search keyword (no wildcard):

https://example/feed/?s=hello+world&post_type=post&exact=1

Query parameter: sentence

The sentence query search parameter can be used to match the whole keyword sentence (no word split):

https://example/feed/?s=hello+world&post_type=post&sentence=1

All together:

https://example/feed/?s=hello+world&post_type=post&exact=1&sentence=1
