• Performing a fuzzy search may retrieve terms with similar spellings: (((("nguoi my hoc phi.") OR ("nguoi my hoc phap."))) OR ("nguoi co hoc phi."))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"nguoi my hoc phi.\") OR (\"nguoi my hoc phap.\"))) OR (\"nguoi co hoc phi.\"))".
• Removing quotes may allow a broader search: (((( nguoi my hoc phi. ) OR ( nguoi my hoc phap. ))) OR ( nguoi co hoc phi. )).
• Adding a wildcard symbol may retrieve word variants: (((("nguoi my hoc phi.") OR ("nguoi my hoc phap."))) OR ("nguoi co hoc phi."))*.
