• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ty nang mai hoi. hieu ((ve cam) OR (ve cac)) ((cuc ban) or (cac ban)) hang tai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty nang mai hoi. hieu ((ve cam) OR (ve cac)) ((cuc ban) OR (cac ban)) hang tai cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty nang mai hoi. hieu ((ve cam) OR (ve cac)) ((cuc ban) or (cac ban)) hang tai cua te*".
