• Performing a fuzzy search may retrieve terms with similar spellings: thuoc sach ky nang ma hoi. hieu ((ve cac) or (vien dai)) ((luc ban) OR (duc ban)) thanh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuoc sach ky nang ma hoi. hieu ((ve cac) OR (vien dai)) ((luc ban) OR (duc ban)) thanh vi cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuoc sach ky nang ma hoi. hieu ((ve cac) or (vien dai)) ((luc ban) OR (duc ban)) thanh vi cua te*".
