• Performing a fuzzy search may retrieve terms with similar spellings: vu ((sach ky) OR (sac ky)) lang ha hoi. hieu va ((nay thuc) or (day thuc)) va thanh doi cua tuc~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu ((sach ky) OR (sac ky)) lang ha hoi. hieu va ((nay thuc) OR (day thuc)) va thanh doi cua tuc.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu ((sach ky) OR (sac ky)) lang ha hoi. hieu va ((nay thuc) or (day thuc)) va thanh doi cua tuc".
• Adding a wildcard symbol may retrieve word variants: vu ((sach ky) OR (sac ky)) lang ha hoi. hieu va ((nay thuc) or (day thuc)) va thanh doi cua tuc*.
