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