• If you are trying to use Boolean operators, they must be ALL CAPS: ((thuat sach) OR (tu sach)) ky nang xa hoi. lieu va cam xuc van thanh ((de cua) OR (te cua)) te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thuat sach) or (tu sach)) ky nang xa hoi. lieu va cam xuc van thanh ((de cua) OR (te cua)) te".
• Adding a wildcard symbol may retrieve word variants: ((thuat sach) or (tu sach)) ky nang xa hoi. lieu va cam xuc van thanh ((de cua) OR (te cua)) te*.
