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