• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu tinh - anh trong quang ((dung thuong) OR (dung trong)) dan ((thanh hai) OR (hanh mau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu tinh - anh trong quang ((dung thuong) OR (dung trong)) dan ((thanh hai) or (hanh mau))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu tinh - anh trong quang ((dung thuong) OR (dung trong)) dan ((thanh hai) or (hanh mau))*.
