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