• Performing a fuzzy search may retrieve terms with similar spellings: su sach ty nang co hoc. hieu vu nham thuc va phan ((((lap cua) OR (lam cua))) or (tap cua)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty nang co hoc. hieu vu nham thuc va phan ((((lap cua) OR (lam cua))) OR (tap cua)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty nang co hoc. hieu vu nham thuc va phan ((((lap cua) OR (lam cua))) or (tap cua)) triet".
• Adding a wildcard symbol may retrieve word variants: su sach ty nang co hoc. hieu vu nham thuc va phan ((((lap cua) OR (lam cua))) or (tap cua)) triet*.
