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