• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((thu hang) OR (thu huong)) mai hoi. hieu ve cac xuc van vanh dai ((cua tu) or (cua cu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((thu hang) OR (thu huong)) mai hoi. hieu ve cac xuc van vanh dai ((cua tu) OR (cua cu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((thu hang) OR (thu huong)) mai hoi. hieu ve cac xuc van vanh dai ((cua tu) or (cua cu))".
• Adding a wildcard symbol may retrieve word variants: te sach ((thu hang) OR (thu huong)) mai hoi. hieu ve cac xuc van vanh dai ((cua tu) or (cua cu))*.
