Perhaps you should try some spelling variations:
"industrial development center survey" » "industrial development case survey", "industrial development sector survey", "industrial development center series"
"industrial procurement agent series" » "industrial procurement act series", "industrial procurement audit series", "industrial procurement market series", "industrial procurement age series", "industrial procurement ages series", "industrial procurement orient series"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"industrial procurement agent series\") OR (\"industrial development center survey\"))~".
• Removing quotes may allow a broader search: (( industrial procurement agent series ) OR ( industrial development center survey ))~.
• Adding a wildcard symbol may retrieve word variants: (("industrial procurement agent series") OR ("industrial development center survey"))*.
