• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - hanh truong ((dap nhung) OR (va nhung)) chong van ((tan ban) OR (van ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - hanh truong ((dap nhung) OR (va nhung)) chong van ((tan ban) or (van ban))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - hanh truong ((dap nhung) OR (va nhung)) chong van ((tan ban) or (van ban))*.
