• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach ty) OR (sach y)) hoang xa hoi. lieu va lap duoc ban ban vi ((cua tre) or (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ty) OR (sach y)) hoang xa hoi. lieu va lap duoc ban ban vi ((cua tre) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ty) OR (sach y)) hoang xa hoi. lieu va lap duoc ban ban vi ((cua tre) or (cua te))".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ty) OR (sach y)) hoang xa hoi. lieu va lap duoc ban ban vi ((cua tre) or (cua te))*.
