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