• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang ma hoi. lieu va cam ((luc va) OR (loc va)) hanh ((tai cua) OR (tri cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang ma hoi. lieu va cam ((luc va) or (loc va)) hanh ((tai cua) OR (tri cua)) tre".
