• Performing a fuzzy search may retrieve terms with similar spellings: (((("lang thuy lich.") OR ("lang thuc lich."))) OR ("dang thuy lich."))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"lang thuy lich.\") OR (\"lang thuc lich.\"))) OR (\"dang thuy lich.\"))*".
• Removing quotes may allow a broader search: (((( lang thuy lich. ) OR ( lang thuc lich. ))) OR ( dang thuy lich. ))*.
