• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ty nang xa hoi. thien van cac cay va thanh ((((lap cua) OR (lai cua))) or (lam cua)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty nang xa hoi. thien van cac cay va thanh ((((lap cua) OR (lai cua))) OR (lam cua)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty nang xa hoi. thien van cac cay va thanh ((((lap cua) OR (lai cua))) or (lam cua)) triet".
• Adding a wildcard symbol may retrieve word variants: tu sach ty nang xa hoi. thien van cac cay va thanh ((((lap cua) OR (lai cua))) or (lam cua)) triet*.
