• Performing a fuzzy search may retrieve terms with similar spellings: te cac ky dang xay hoi. hieu ((((va cam) OR (va cham))) or (va phat)) duc va nang tai ca tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te cac ky dang xay hoi. hieu ((((va cam) OR (va cham))) OR (va phat)) duc va nang tai ca tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te cac ky dang xay hoi. hieu ((((va cam) OR (va cham))) or (va phat)) duc va nang tai ca tren".
• Adding a wildcard symbol may retrieve word variants: te cac ky dang xay hoi. hieu ((((va cam) OR (va cham))) or (va phat)) duc va nang tai ca tren*.
