• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach ky) OR (sach y)) nang so hai. hieu ((va cam) or (va cac)) xuc ban anh di cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ky) OR (sach y)) nang so hai. hieu ((va cam) OR (va cac)) xuc ban anh di cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) OR (sach y)) nang so hai. hieu ((va cam) or (va cac)) xuc ban anh di cuu tre".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ky) OR (sach y)) nang so hai. hieu ((va cam) or (va cac)) xuc ban anh di cuu tre*.
