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