• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ty) OR (((sach lo) OR (sach doi)))) nang xa hoi. hieu van cau xuc va hang doi cua viet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ty) or (((sach lo) OR (sach doi)))) nang xa hoi. hieu van cau xuc va hang doi cua viet~".
• Adding a wildcard symbol may retrieve word variants: te ((sach ty) or (((sach lo) OR (sach doi)))) nang xa hoi. hieu van cau xuc va hang doi cua viet*.
