• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ty nang x hoi. hieu ve cam ((tuc va) OR (tuc xa)) thanh hai ((cua te) OR (cua cau)).
• Adding a wildcard symbol may retrieve word variants: thu sach ty nang x hoi. hieu ve cam ((tuc va) or (tuc xa)) thanh hai ((cua te) or (cua cau))*.
