• Performing a fuzzy search may retrieve terms with similar spellings: ((((vu sac) OR (va sac))) or (vu san)) ky nang ma hoa. hieu de dat ngoc va danh di cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((vu sac) OR (va sac))) OR (vu san)) ky nang ma hoa. hieu de dat ngoc va danh di cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((vu sac) OR (va sac))) or (vu san)) ky nang ma hoa. hieu de dat ngoc va danh di cua tre*".
