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