Hi,

Searching currently not doable on non-database field. It’s doable when you make (non-db) array based grid 

If in database driven grid, there is some field which uses database function, e.g. “SELECT concat(firstname,lastname) as fullname…” then you need to set ‘dbname’ property with that column.

$col["name"] = "fullname";
$col["dbname"] = "concat(firstname,lastname)";
