• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach ki nang cho hoc. hieu ve ((cac xuc) OR (((cac nuoc) OR (cap nuoc)))) van minh doi cua cac*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach ki nang cho hoc. hieu ve ((cac xuc) or (((cac nuoc) OR (cap nuoc)))) van minh doi cua cac*".
