• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((ty nang) OR (ty hang)) x ho. hieu ((ve cai) OR (va cam)) quoc gia thanh ho cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((ty nang) OR (ty hang)) x ho. hieu ((ve cai) or (va cam)) quoc gia thanh ho cua te".
• Adding a wildcard symbol may retrieve word variants: te sach ((ty nang) OR (ty hang)) x ho. hieu ((ve cai) or (va cam)) quoc gia thanh ho cua te*.
