• Performing a fuzzy search may retrieve terms with similar spellings: vu sach tu ((hang xa) OR (hang ca)) hoi. hieu ve cam xuc van hang di ((cua viet) or (va triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach tu ((hang xa) OR (hang ca)) hoi. hieu ve cam xuc van hang di ((cua viet) OR (va triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach tu ((hang xa) OR (hang ca)) hoi. hieu ve cam xuc van hang di ((cua viet) or (va triet))*".
