• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y nang xa hoi. hieu vu cham tuc ((vay doanh) OR (ly doanh)) ((vang cua) OR (tang cua)) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y nang xa hoi. hieu vu cham tuc ((vay doanh) OR (ly doanh)) ((vang cua) or (tang cua)) tre~".
• Adding a wildcard symbol may retrieve word variants: tu sach y nang xa hoi. hieu vu cham tuc ((vay doanh) OR (ly doanh)) ((vang cua) or (tang cua)) tre*.
