• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"phong thi quen hanh. thoi huyen thuat lap\") OR (\"nhung thi luan van. thoi quen tu lap\"))".
• Removing quotes may allow a broader search: (( phong thi quen hanh. thoi huyen thuat lap ) OR ( nhung thi luan van. thoi quen tu lap )).
• Adding a wildcard symbol may retrieve word variants: (("phong thi quen hanh. thoi huyen thuat lap") OR ("nhung thi luan van. thoi quen tu lap"))*.
