• Performing a fuzzy search may retrieve terms with similar spellings: (( co giao su ((triet thu) OR (trien thi)) ) or ((((( pho giao duc tieu chua ) or ( pho gia duc tieu thu ))) or ( pho giao duoc lieu chua ))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( co giao su ((triet thu) OR (trien thi)) ) OR ((((( pho giao duc tieu chua ) OR ( pho gia duc tieu thu ))) OR ( pho giao duoc lieu chua )))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( co giao su ((triet thu) OR (trien thi)) ) or ((((( pho giao duc tieu chua ) or ( pho gia duc tieu thu ))) or ( pho giao duoc lieu chua ))))".
• Adding a wildcard symbol may retrieve word variants: (( co giao su ((triet thu) OR (trien thi)) ) or ((((( pho giao duc tieu chua ) or ( pho gia duc tieu thu ))) or ( pho giao duoc lieu chua ))))*.
