• If you are trying to use Boolean operators, they must be ALL CAPS: vu san ky nang ma hoi. ((thien van) OR (lieu va)) cam luc va nang ((gia cua) OR (giau cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu san ky nang ma hoi. ((thien van) or (lieu va)) cam luc va nang ((gia cua) OR (giau cua)) tre".
• Adding a wildcard symbol may retrieve word variants: vu san ky nang ma hoi. ((thien van) or (lieu va)) cam luc va nang ((gia cua) OR (giau cua)) tre*.
