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