• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ((ky dong) OR (ly dong)) ha noi. hieu van ((cham duc) OR (pham duc)) ban hang vai cua tuc.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ((ky dong) OR (ly dong)) ha noi. hieu van ((cham duc) or (pham duc)) ban hang vai cua tuc".
• Adding a wildcard symbol may retrieve word variants: su sac ((ky dong) OR (ly dong)) ha noi. hieu van ((cham duc) or (pham duc)) ban hang vai cua tuc*.
