• Performing a fuzzy search may retrieve terms with similar spellings: so sac ky nang x hoi. ((hieu ve) OR (hieu va)) cam luc va ((hanh cua) or (hang cua)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sac ky nang x hoi. ((hieu ve) OR (hieu va)) cam luc va ((hanh cua) OR (hang cua)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sac ky nang x hoi. ((hieu ve) OR (hieu va)) cam luc va ((hanh cua) or (hang cua)) cua triet".
• Adding a wildcard symbol may retrieve word variants: so sac ky nang x hoi. ((hieu ve) OR (hieu va)) cam luc va ((hanh cua) or (hang cua)) cua triet*.
