• Performing a fuzzy search may retrieve terms with similar spellings: su ((sach ly) or (sach ty)) nang ma hoi. hieu va cam tuc va ((danh hai) OR (lanh hai)) cau treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach ly) OR (sach ty)) nang ma hoi. hieu va cam tuc va ((danh hai) OR (lanh hai)) cau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ly) or (sach ty)) nang ma hoi. hieu va cam tuc va ((danh hai) OR (lanh hai)) cau treo".
• Adding a wildcard symbol may retrieve word variants: su ((sach ly) or (sach ty)) nang ma hoi. hieu va cam tuc va ((danh hai) OR (lanh hai)) cau treo*.
