Perhaps you should try some spelling variations:
"industrial procurement agencies series" » "industrial procurement agents series", "industrial procurement policies series", "industrial procurement agent series", "industrial procurement agencies saras", "industrial procurement agencies overview"
"industrial development center survey" » "industrial development case survey", "industrial development sector survey", "industrial development center 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 development center survey\") OR (\"industrial procurement agencies series\"))~".
• Removing quotes may allow a broader search: (( industrial development center survey ) OR ( industrial procurement agencies series ))~.
• Adding a wildcard symbol may retrieve word variants: (("industrial development center survey") OR ("industrial procurement agencies series"))*.
