- If you are trying to use Boolean operators, they must be ALL CAPS: "((\"khoa hoc van ((chat pha) OR (chat thai))\") or (\"khoa hoc ((dan than) OR (dan chan)) pha\"))".
- The words AND, OR and NOT may confuse the search; try adding quotes: "\"((\\"khoa hoc van ((chat pha) OR (chat thai))\\") or (\\"khoa hoc ((dan than) or (dan chan)) pha\\"))\"".
- Removing quotes may allow a broader search: (( khoa hoc van ((chat pha) OR (chat thai)) ) or ( khoa hoc ((dan than) or (dan chan)) pha )).
