• If you are trying to use Boolean operators, they must be ALL CAPS: doi hieu lang - manh trung cua ((nhung huong) OR (truong phuong)) dan ((than cao) OR (thai cao))~.
• Adding a wildcard symbol may retrieve word variants: doi hieu lang - manh trung cua ((nhung huong) or (truong phuong)) dan ((than cao) or (thai cao))*.
