• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ky ((nang tai) OR (sang tai)) hoi. ((hieu qua) or (bieu cua)) dat nuoc va hanh ca cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky ((nang tai) OR (sang tai)) hoi. ((hieu qua) OR (bieu cua)) dat nuoc va hanh ca cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky ((nang tai) OR (sang tai)) hoi. ((hieu qua) or (bieu cua)) dat nuoc va hanh ca cua tre*".
