• Performing a fuzzy search may retrieve terms with similar spellings: tu sach y dang van hoc. lieu va cam ((((lo van) OR (le van))) or (vo van)) thanh toan cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y dang van hoc. lieu va cam ((((lo van) OR (le van))) OR (vo van)) thanh toan cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y dang van hoc. lieu va cam ((((lo van) OR (le van))) or (vo van)) thanh toan cua te".
• Adding a wildcard symbol may retrieve word variants: tu sach y dang van hoc. lieu va cam ((((lo van) OR (le van))) or (vo van)) thanh toan cua te*.
