Please disregard!
I found the answer in the documentation itself, apologies.
The solution was to write a plugin, as below, corresponding to my above use case:
`
add_filter(“asp_query_args”, “filter_search_by_user_uuid”, 10, 2);
function filter_search_by_user_uuid($args, $search_id) {
// Replace ‘2’ with the ID of your specific search bar
$target_search_id = 2;
if ($search_id != $target_search_id) {
// If this isn’t the target search bar, don’t modify the query
return $args;
}
// Get the current user ID and retrieve their UUID
$current_user_id = get_current_user_id();
$user_uuid = get_user_meta($current_user_id, ‘user-uuid’, true);
// Check if user UUID is available
if ($user_uuid) {
// Add a post meta filter to the query arguments
$args[‘post_meta_filter’] = array(
array(
‘key’ => ‘user-uuid’,
‘value’ => $user_uuid,
‘operator’ => ‘=’,
‘allow_missing’ => false
)
);
}
return $args;
}
`
