Perhaps you should try some spelling variations:
"yonse taehakkyo / emission" » "yonge taehakkyo / emission", "bonse taehakkyo / emission", "konse taehakkyo / emission"
"yonsei taehakkyo / emission" » "yongei taehakkyo / emission", "bonsei taehakkyo / emission", "konsei taehakkyo / emission"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("yonse taehakkyo / emission") OR ("yonsei taehakkyo / emission"))) OR ("conse taehakkyo / emission")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"yonse taehakkyo / emission\") OR (\"yonsei taehakkyo / emission\"))) or (\"conse taehakkyo / emission\"))".
• Removing quotes may allow a broader search: (((( yonse taehakkyo / emission ) OR ( yonsei taehakkyo / emission ))) or ( conse taehakkyo / emission )).
• Adding a wildcard symbol may retrieve word variants: (((("yonse taehakkyo / emission") OR ("yonsei taehakkyo / emission"))) or ("conse taehakkyo / emission"))*.
