• Performing a fuzzy search may retrieve terms with similar spellings: (( (phung OR phong) thi que lang. nuoi duong hoc mo ) or ( nhung thi biet lang. noi dung co ma ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( (phung OR phong) thi que lang. nuoi duong hoc mo ) OR ( nhung thi biet lang. noi dung co ma )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( (phung OR phong) thi que lang. nuoi duong hoc mo ) or ( nhung thi biet lang. noi dung co ma ))".
• Adding a wildcard symbol may retrieve word variants: (( (phung OR phong) thi que lang. nuoi duong hoc mo ) or ( nhung thi biet lang. noi dung co ma ))*.
