Perhaps you should try some spelling variations:
specific proposals » specific protocols, specific purposes, specific process
specific protocol » specific protection, specific proteomic, specific protein
proposals recipes » proposals review, protocols recipes, proposals previous
protocol reports » protocols ports, protocol results, protocol deserts

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: (( specific protocol reports ) OR ( specific proposals recipes )).
• Adding a wildcard symbol may retrieve word variants: (( specific protocol reports ) or ( specific proposals recipes ))*.
