• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ty nang xa hoi. hieu viec lam lo ((van danh) or (((van hanh) OR (ban hanh)))) vai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ty nang xa hoi. hieu viec lam lo ((van danh) OR (((van hanh) OR (ban hanh)))) vai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ty nang xa hoi. hieu viec lam lo ((van danh) or (((van hanh) OR (ban hanh)))) vai cua tre*".
