• Performing a fuzzy search may retrieve terms with similar spellings: vu bach ly nang xa hoi. thien van cam ((luc ban) OR (cuc ban)) ((thanh va) or (thanh ha)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu bach ly nang xa hoi. thien van cam ((luc ban) OR (cuc ban)) ((thanh va) OR (thanh ha)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu bach ly nang xa hoi. thien van cam ((luc ban) OR (cuc ban)) ((thanh va) or (thanh ha)) cua tre".
• Adding a wildcard symbol may retrieve word variants: vu bach ly nang xa hoi. thien van cam ((luc ban) OR (cuc ban)) ((thanh va) or (thanh ha)) cua tre*.
