• If you are trying to use Boolean operators, they must be ALL CAPS: (((( thuc hanh kem dinh duc. ) OR ( thep tinh cam tinh doc. ))) OR ( thieu quang lam tinh bac. ))~.
• Adding a wildcard symbol may retrieve word variants: (((( thuc hanh kem dinh duc. ) or ( thep tinh cam tinh doc. ))) or ( thieu quang lam tinh bac. ))*.
