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