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

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: ((research process) OR (((research processes) OR (research procedures)))).
• Adding a wildcard symbol may retrieve word variants: ((research process) or (((research processes) or (research procedures))))*.
