• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ((ly nang) OR (ly hang)) xa hoi. hieu va ((cham xuc) OR (cham soc)) va hanh vi cua tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ((ly nang) or (ly hang)) xa hoi. hieu va ((cham xuc) OR (cham soc)) va hanh vi cua tu".
• Adding a wildcard symbol may retrieve word variants: thu sach ((ly nang) or (ly hang)) xa hoi. hieu va ((cham xuc) OR (cham soc)) va hanh vi cua tu*.
