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