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