• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty nang x hoi. hieu vu cham duc ban doanh va ((cua tre) OR (((cua tuc) OR (cua thuoc))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty nang x hoi. hieu vu cham duc ban doanh va ((cua tre) or (((cua tuc) OR (cua thuoc))))~".
• Adding a wildcard symbol may retrieve word variants: tu sach ty nang x hoi. hieu vu cham duc ban doanh va ((cua tre) or (((cua tuc) OR (cua thuoc))))*.
