• Performing a fuzzy search may retrieve terms with similar spellings: (( tu ((hach toc) OR (hach toan)) tay nguoi ) or ( tu cach duoc ((li nguoi) or (ly nguoi)) ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu ((hach toc) OR (hach toan)) tay nguoi ) OR ( tu cach duoc ((li nguoi) OR (ly nguoi)) )).
