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