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