• If you are trying to use Boolean operators, they must be ALL CAPS: su bach dang nang xa hoi. hieu ve cau truc van thanh ((ve cua) OR (((de cua) OR (le cua)))) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su bach dang nang xa hoi. hieu ve cau truc van thanh ((ve cua) or (((de cua) OR (le cua)))) tre~".
• Adding a wildcard symbol may retrieve word variants: su bach dang nang xa hoi. hieu ve cau truc van thanh ((ve cua) or (((de cua) OR (le cua)))) tre*.
