Perhaps you should try some spelling variations:
"specified protocols reports" » "specific protocol reports", "specified protocols ports", "specified protocols records", "specified protocols reporting"
"specific protocols reports" » "specific protocol reports", "specific proposals reports", "scientific protocols reports", "specific protocols ports", "specific protocols records", "specific protocols reporting"

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: "((\"specific protocols reports\") OR (\"specified protocols reports\"))".
• Removing quotes may allow a broader search: (( specific protocols reports ) OR ( specified protocols reports )).
• Adding a wildcard symbol may retrieve word variants: (("specific protocols reports") OR ("specified protocols reports"))*.
