• Performing a fuzzy search may retrieve terms with similar spellings: te bai ky dang xa hoi. hieu ve cac luc ban hang de ((((cua triet) OR (cua viet))) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te bai ky dang xa hoi. hieu ve cac luc ban hang de ((((cua triet) OR (cua viet))) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te bai ky dang xa hoi. hieu ve cac luc ban hang de ((((cua triet) OR (cua viet))) or (cuu tre))".
• Adding a wildcard symbol may retrieve word variants: te bai ky dang xa hoi. hieu ve cac luc ban hang de ((((cua triet) OR (cua viet))) or (cuu tre))*.
