• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sac ky) or (sach tham)) dang xay hoi. hieu va cao xuc va hanh ((dan cua) OR (ban cua)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sac ky) OR (sach tham)) dang xay hoi. hieu va cao xuc va hanh ((dan cua) OR (ban cua)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sac ky) or (sach tham)) dang xay hoi. hieu va cao xuc va hanh ((dan cua) OR (ban cua)) tre*".
