• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ((((dao nang) OR (cao nang))) or (da nang)) mai hoi. hieu va cao xuc ban hanh vi cua tuc~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((((dao nang) OR (cao nang))) OR (da nang)) mai hoi. hieu va cao xuc ban hanh vi cua tuc.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((((dao nang) OR (cao nang))) or (da nang)) mai hoi. hieu va cao xuc ban hanh vi cua tuc".
• Adding a wildcard symbol may retrieve word variants: tu sach ((((dao nang) OR (cao nang))) or (da nang)) mai hoi. hieu va cao xuc ban hanh vi cua tuc*.
