• Performing a fuzzy search may retrieve terms with similar spellings: thuoc sach tu ((mang xa) or (sang ma)) hoi. hieu va cac xuc ban danh hai ((cua te) OR (cua tu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuoc sach tu ((mang xa) OR (sang ma)) hoi. hieu va cac xuc ban danh hai ((cua te) OR (cua tu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuoc sach tu ((mang xa) or (sang ma)) hoi. hieu va cac xuc ban danh hai ((cua te) OR (cua tu))".
• Adding a wildcard symbol may retrieve word variants: thuoc sach tu ((mang xa) or (sang ma)) hoi. hieu va cac xuc ban danh hai ((cua te) OR (cua tu))*.
