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