• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ty) OR (((sai ky) OR (sac ky)))) nang xa hoi. hieu va cau truc va hanh va chua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ty) or (((sai ky) OR (sac ky)))) nang xa hoi. hieu va cau truc va hanh va chua triet~".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ty) or (((sai ky) OR (sac ky)))) nang xa hoi. hieu va cau truc va hanh va chua triet*.
