• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky ((mang xa) OR (nang x)) hoi. hieu va cac xuc va tinh ((ve cua) OR (le cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky ((mang xa) or (nang x)) hoi. hieu va cac xuc va tinh ((ve cua) OR (le cua)) tre".
