• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach lo) OR (((sach doi) OR (sach hoi)))) lang xa hoi. thi van dau xuc va hanh vai cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach lo) or (((sach doi) OR (sach hoi)))) lang xa hoi. thi van dau xuc va hanh vai cua triet~".
• Adding a wildcard symbol may retrieve word variants: thu ((sach lo) or (((sach doi) OR (sach hoi)))) lang xa hoi. thi van dau xuc va hanh vai cua triet*.
