• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach ky) OR (sac ky)) ((tang xa) or (trang xa)) hoi. hieu vien bach xuc gia thanh va cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ky) OR (sac ky)) ((tang xa) OR (trang xa)) hoi. hieu vien bach xuc gia thanh va cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) OR (sac ky)) ((tang xa) or (trang xa)) hoi. hieu vien bach xuc gia thanh va cuu tre".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ky) OR (sac ky)) ((tang xa) or (trang xa)) hoi. hieu vien bach xuc gia thanh va cuu tre*.
