• Performing a fuzzy search may retrieve terms with similar spellings: ((vu thanh) OR (cuu thanh)) ky dinh va hoi. hieu van lam luc va thanh ve ((cua tre) or (cua tu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu thanh) OR (cuu thanh)) ky dinh va hoi. hieu van lam luc va thanh ve ((cua tre) OR (cua tu))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu thanh) OR (cuu thanh)) ky dinh va hoi. hieu van lam luc va thanh ve ((cua tre) or (cua tu))*".
