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