• Performing a fuzzy search may retrieve terms with similar spellings: thuoc sach ky nang ma hoi. hieu ((ve cham) or (vu cham)) ((xuc gia) OR (luc gia)) thanh hai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuoc sach ky nang ma hoi. hieu ((ve cham) OR (vu cham)) ((xuc gia) OR (luc gia)) thanh hai cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuoc sach ky nang ma hoi. hieu ((ve cham) or (vu cham)) ((xuc gia) OR (luc gia)) thanh hai cuu tre".
