• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky nang xa hoi. hieu va cam xuc van hanh vi ((((cua thep) or (cua te))) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang xa hoi. hieu va cam xuc van hanh vi ((((cua thep) OR (cua te))) OR (cuu tre)).
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang xa hoi. hieu va cam xuc van hanh vi ((((cua thep) or (cua te))) or (cuu tre))*.
