• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu dan) OR (tu ban)) ky ((mang xa) OR (nang x)) hoi. hieu ve cam tuc va hanh kem ca tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu dan) OR (tu ban)) ky ((mang xa) or (nang x)) hoi. hieu ve cam tuc va hanh kem ca tren".
• Adding a wildcard symbol may retrieve word variants: ((tu dan) OR (tu ban)) ky ((mang xa) or (nang x)) hoi. hieu ve cam tuc va hanh kem ca tren*.
