Perhaps you should try some spelling variations:
"research procedures" » "search procedures", "search procedure", "research proceedings"
"research problemses" » "research problems", "research problem", "research problemy"
"research progresses" » "research progress", "research programmes", "research congresses"
"research processes" » "research progress", "research practices", "search process", "research progresses", "research problemses", "research projectes"
"research projects" » "research project"
"research process" » "research progress", "research problems", "research project"

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 processes") OR ("research procedures"))) OR ((("research problemses") OR ("research progresses"))))) OR ((("research process") OR ("research projects")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"research processes\") OR (\"research procedures\"))) or (((\"research problemses\") or (\"research progresses\"))))) or (((\"research process\") or (\"research projects\"))))".
• Removing quotes may allow a broader search: (((((( research processes ) OR ( research procedures ))) or ((( research problemses ) or ( research progresses ))))) or ((( research process ) or ( research projects )))).
• Adding a wildcard symbol may retrieve word variants: (((((("research processes") OR ("research procedures"))) or ((("research problemses") or ("research progresses"))))) or ((("research process") or ("research projects"))))*.
