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