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