• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sai ky) OR (sac ky)) sang lai hoi. hieu ((su chat) OR (su phat)) xuc va hanh vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sai ky) or (sac ky)) sang lai hoi. hieu ((su chat) OR (su phat)) xuc va hanh vi cua te".
• Adding a wildcard symbol may retrieve word variants: tu ((sai ky) or (sac ky)) sang lai hoi. hieu ((su chat) OR (su phat)) xuc va hanh vi cua te*.
