• Performing a fuzzy search may retrieve terms with similar spellings: te sach ty dang xa hoi. hieu ve cham luc va tinh tai ((cuc tre) or (((cua tre) OR (cua triet))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty dang xa hoi. hieu ve cham luc va tinh tai ((cuc tre) OR (((cua tre) OR (cua triet)))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty dang xa hoi. hieu ve cham luc va tinh tai ((cuc tre) or (((cua tre) OR (cua triet))))".
• Adding a wildcard symbol may retrieve word variants: te sach ty dang xa hoi. hieu ve cham luc va tinh tai ((cuc tre) or (((cua tre) OR (cua triet))))*.
