• Performing a fuzzy search may retrieve terms with similar spellings: te ((((sach ky) OR (sac ky))) or (sach y)) nang xa hoi. hieu ve cham tuc va doan ban cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((((sach ky) OR (sac ky))) OR (sach y)) nang xa hoi. hieu ve cham tuc va doan ban cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((((sach ky) OR (sac ky))) or (sach y)) nang xa hoi. hieu ve cham tuc va doan ban cua tre*".
