From the Relevanssi settings, you can only choose whether subscribers are indexed or not.
If you need finer control over what user roles are indexed by Relevanssi, you can use the relevanssi_user_index_ok filter hook with the following code. Place it in your theme functions.php:
add_filter( 'relevanssi_user_index_ok', 'rlv_do_not_index_admins', 10, 2 );
function rlv_do_not_index_admins( $do_index, $user ) {
$block_these_roles = array(
'administrator',
'editor',
'author',
'contributor',
'subscriber'
);
$vars = get_object_vars( $user );
if ( is_array( $vars['caps'] ) ) {
foreach ( array_keys( $vars['caps'] ) as $role ) {
if ( in_array( $role, $block_these_roles, true ) ) {
$do_index = false;
break;
}
}
}
return $do_index;
}Just adjust the $block_these_roles array to include the roles you want to exclude from the index.
