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