• Performing a fuzzy search may retrieve terms with similar spellings: su sac ky tang xa hoi. thien van cam ((duc ban) OR (duc van)) ((thanh hai) or (thanh hoa)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky tang xa hoi. thien van cam ((duc ban) OR (duc van)) ((thanh hai) OR (thanh hoa)) cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky tang xa hoi. thien van cam ((duc ban) OR (duc van)) ((thanh hai) or (thanh hoa)) cua tre*".
