• If you are trying to use Boolean operators, they must be ALL CAPS: te sach v nang xa hoi. hieu ((va tham) OR (va thanh)) nuoc va danh ((lien cuc) OR (lien tuc)) te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach v nang xa hoi. hieu ((va tham) OR (va thanh)) nuoc va danh ((lien cuc) or (lien tuc)) te".
• Adding a wildcard symbol may retrieve word variants: te sach v nang xa hoi. hieu ((va tham) OR (va thanh)) nuoc va danh ((lien cuc) or (lien tuc)) te*.
