• If you are trying to use Boolean operators, they must be ALL CAPS: te sach lo hang ca hoi. hieu va cam ((((xuc va) OR (tuc va))) OR (luc va)) danh vi cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach lo hang ca hoi. hieu va cam ((((xuc va) OR (tuc va))) or (luc va)) danh vi cua triet*".
