• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ((tru nang) OR (truc nano)) x hoi. hieu ve cam xuc va hanh ((vai cua) OR (doi cua)) triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ((tru nang) OR (truc nano)) x hoi. hieu ve cam xuc va hanh ((vai cua) or (doi cua)) triet*".
