• If you are trying to use Boolean operators, they must be ALL CAPS: vu bach ty ((hang ca) OR (hang va)) hoi. hieu van cam xuc ban ((thanh ve) OR (thanh vien)) cua tuc.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu bach ty ((hang ca) OR (hang va)) hoi. hieu van cam xuc ban ((thanh ve) or (thanh vien)) cua tuc".
• Adding a wildcard symbol may retrieve word variants: vu bach ty ((hang ca) OR (hang va)) hoi. hieu van cam xuc ban ((thanh ve) or (thanh vien)) cua tuc*.
