• Performing a fuzzy search may retrieve terms with similar spellings: so ((sach va) OR (sach xa)) tang ma hoi. hieu ve cam tuc van anh di ((cua duc) or (cua cu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so ((sach va) OR (sach xa)) tang ma hoi. hieu ve cam tuc van anh di ((cua duc) OR (cua cu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "so ((sach va) OR (sach xa)) tang ma hoi. hieu ve cam tuc van anh di ((cua duc) or (cua cu))".
• Adding a wildcard symbol may retrieve word variants: so ((sach va) OR (sach xa)) tang ma hoi. hieu ve cam tuc van anh di ((cua duc) or (cua cu))*.
