• Performing a fuzzy search may retrieve terms with similar spellings: te ((sach ky) or (sach y)) lang xa hoi. thien van cau xuc va dinh va ((cau tre) OR (cau tra))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ky) OR (sach y)) lang xa hoi. thien van cau xuc va dinh va ((cau tre) OR (cau tra)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) or (sach y)) lang xa hoi. thien van cau xuc va dinh va ((cau tre) OR (cau tra))".
• Adding a wildcard symbol may retrieve word variants: te ((sach ky) or (sach y)) lang xa hoi. thien van cau xuc va dinh va ((cau tre) OR (cau tra))*.
