• Performing a fuzzy search may retrieve terms with similar spellings: te ((sach ky) OR (sac ky)) nang xa hoi. thi nang ((cham duc) or (cham soc)) va danh vinh cau tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ky) OR (sac ky)) nang xa hoi. thi nang ((cham duc) OR (cham soc)) va danh vinh cau tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) OR (sac ky)) nang xa hoi. thi nang ((cham duc) or (cham soc)) va danh vinh cau tren".
• Adding a wildcard symbol may retrieve word variants: te ((sach ky) OR (sac ky)) nang xa hoi. thi nang ((cham duc) or (cham soc)) va danh vinh cau tren*.
