• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky dang ha hoi. hieu ve cac tac ((van doanh) OR (van thanh)) ((van cua) OR (vang cua)) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky dang ha hoi. hieu ve cac tac ((van doanh) OR (van thanh)) ((van cua) or (vang cua)) tre~".
• Adding a wildcard symbol may retrieve word variants: te sac ky dang ha hoi. hieu ve cac tac ((van doanh) OR (van thanh)) ((van cua) or (vang cua)) tre*.
