• Performing a fuzzy search may retrieve terms with similar spellings: (("van hoa thoi ky van duong.") OR ("van hoc hoi ky van duong."))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"van hoa thoi ky van duong.\") OR (\"van hoc hoi ky van duong.\"))*".
• Removing quotes may allow a broader search: (( van hoa thoi ky van duong. ) OR ( van hoc hoi ky van duong. ))*.
