• Performing a fuzzy search may retrieve terms with similar spellings: te sach 7 long ha hoi. hieu ((ve cam) or (vien cac)) ((tuc va) OR (tuc xa)) thanh va cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach 7 long ha hoi. hieu ((ve cam) OR (vien cac)) ((tuc va) OR (tuc xa)) thanh va cuu tre.
