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