• If you are trying to use Boolean operators, they must be ALL CAPS: pu bac ky nang xa hoi. lieu va cam ((xuc ban) OR (cuc ban)) doanh ((tai cua) OR (tri cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "pu bac ky nang xa hoi. lieu va cam ((xuc ban) or (cuc ban)) doanh ((tai cua) OR (tri cua)) tre".
