• If you are trying to use Boolean operators, they must be ALL CAPS: ((chao chu) OR (cua chu)) manh - hanh ban cua dung cong trinh ((toan cau) OR (toan cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((chao chu) OR (cua chu)) manh - hanh ban cua dung cong trinh ((toan cau) or (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: ((chao chu) OR (cua chu)) manh - hanh ban cua dung cong trinh ((toan cau) or (toan cao))*.
