• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ((tu nang) or (tru nang)) xa hoi. hieu va cac xuc van ((thanh van) OR (thanh phan)) cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((tu nang) OR (tru nang)) xa hoi. hieu va cac xuc van ((thanh van) OR (thanh phan)) cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((tu nang) or (tru nang)) xa hoi. hieu va cac xuc van ((thanh van) OR (thanh phan)) cuu tre".
• Adding a wildcard symbol may retrieve word variants: tu sach ((tu nang) or (tru nang)) xa hoi. hieu va cac xuc van ((thanh van) OR (thanh phan)) cuu tre*.
