• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho lieu) OR (ho kieu)) tinh - nhanh lang luan ((nhung dung) OR (nhung phuong)) dan than tap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho lieu) OR (ho kieu)) tinh - nhanh lang luan ((nhung dung) or (nhung phuong)) dan than tap".
• Adding a wildcard symbol may retrieve word variants: ((ho lieu) OR (ho kieu)) tinh - nhanh lang luan ((nhung dung) or (nhung phuong)) dan than tap*.
