• Performing a fuzzy search may retrieve terms with similar spellings: thu ((sach ky) OR (sac ky)) nang xa hoi. ((hieu va) or (lieu va)) cham xuc va han thai va thiet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach ky) OR (sac ky)) nang xa hoi. ((hieu va) OR (lieu va)) cham xuc va han thai va thiet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach ky) OR (sac ky)) nang xa hoi. ((hieu va) or (lieu va)) cham xuc va han thai va thiet*".
