• Removing quotes may allow a broader search: (((( thep thanh lap trinh doc. ) OR ( thep tanh lap trinh f.c. ))) OR ( thuc hanh kem dinh duc. ))~.
• Adding a wildcard symbol may retrieve word variants: (((("thep thanh lap trinh doc.") OR ("thep tanh lap trinh f.c."))) OR ("thuc hanh kem dinh duc."))*.
