• Performing a fuzzy search may retrieve terms with similar spellings: thu sac ((ky dang) OR (ky nang)) ha noi. hieu vu cham ((xuc van) or (duc van)) thanh te cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sac ((ky dang) OR (ky nang)) ha noi. hieu vu cham ((xuc van) OR (duc van)) thanh te cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sac ((ky dang) OR (ky nang)) ha noi. hieu vu cham ((xuc van) or (duc van)) thanh te cua tre".
• Adding a wildcard symbol may retrieve word variants: thu sac ((ky dang) OR (ky nang)) ha noi. hieu vu cham ((xuc van) or (duc van)) thanh te cua tre*.
