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