• Performing a fuzzy search may retrieve terms with similar spellings: tu dan ((ky va) OR (my va)) xay hoi. hieu ve cac xuc va hanh vi ((cua tre) or (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu dan ((ky va) OR (my va)) xay hoi. hieu ve cac xuc va hanh vi ((cua tre) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu dan ((ky va) OR (my va)) xay hoi. hieu ve cac xuc va hanh vi ((cua tre) or (cua te))".
• Adding a wildcard symbol may retrieve word variants: tu dan ((ky va) OR (my va)) xay hoi. hieu ve cac xuc va hanh vi ((cua tre) or (cua te))*.
