Perhaps you should try some spelling variations:
"process control service methodology." » "process control sciences methodology.", "process control devices methodology.", "procesos control service methodology.", "procesal control service methodology."
"proceso control science methodology." » "proceso control sciences meteorology.", "proceso control science anthropology.", "proceso contra science methodology.", "proceso contralos science methodology.", "proces contre science methodology."

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: "((\"process control service methodology.\") OR (\"proceso control science methodology.\"))~".
• Removing quotes may allow a broader search: (( process control service methodology. ) OR ( proceso control science methodology. ))~.
• Adding a wildcard symbol may retrieve word variants: (("process control service methodology.") OR ("proceso control science methodology."))*.
