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