• Performing a fuzzy search may retrieve terms with similar spellings: toc ((sach ty) OR (sach y)) hang va hoi. hieu va cham soc va hanh di ((cua te) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc ((sach ty) OR (sach y)) hang va hoi. hieu va cham soc va hanh di ((cua te) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((sach ty) OR (sach y)) hang va hoi. hieu va cham soc va hanh di ((cua te) or (cuu tre))*".
