• Performing a fuzzy search may retrieve terms with similar spellings: ((su sac) OR (su sach)) hoi lang xa hoi. hieu va chat tuc ((va dinh) or (va tinh)) va cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sac) OR (su sach)) hoi lang xa hoi. hieu va chat tuc ((va dinh) OR (va tinh)) va cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sac) OR (su sach)) hoi lang xa hoi. hieu va chat tuc ((va dinh) or (va tinh)) va cua tre*".
