• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty nang cao hoi. lieu va ((cau vuc) OR (cau luc)) ((van han) OR (van nhan)) tri cua tuc.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty nang cao hoi. lieu va ((cau vuc) OR (cau luc)) ((van han) or (van nhan)) tri cua tuc".
• Adding a wildcard symbol may retrieve word variants: te sach ty nang cao hoi. lieu va ((cau vuc) OR (cau luc)) ((van han) or (van nhan)) tri cua tuc*.
