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