• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ky nang tao hoi. hieu va ((cham tuc) OR (nham thuc)) va thanh hai ((dua tren) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ky nang tao hoi. hieu va ((cham tuc) OR (nham thuc)) va thanh hai ((dua tren) or (cua te))".
• Adding a wildcard symbol may retrieve word variants: thu sach ky nang tao hoi. hieu va ((cham tuc) OR (nham thuc)) va thanh hai ((dua tren) or (cua te))*.
