• If you are trying to use Boolean operators, they must be ALL CAPS: tu san ky nang mai hoi. lieu va ((cam tu) OR (dam tu)) va hanh vi ((cua tre) OR (cua triet)).
• Adding a wildcard symbol may retrieve word variants: tu san ky nang mai hoi. lieu va ((cam tu) or (dam tu)) va hanh vi ((cua tre) or (cua triet))*.
