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