Perhaps you should try some spelling variations:
research procedures » search procedures, search procedure, research proceedings
research processes » research process, research projects, research progress
research problems » research progress, research process, research program

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: "(((((( research processes ) OR ( research procedures ))) OR ( research project ))) OR ( research problems ))".
• Adding a wildcard symbol may retrieve word variants: (((((( research processes ) OR ( research procedures ))) OR ( research project ))) OR ( research problems ))*.
