Perhaps you should try some spelling variations:
"process control statistical methodology." » "process control statistics methodology.", "process control statistical methods.", "procesos control statistical methodology.", "procesal control statistical methodology."
"proceso contra devices methodology." » "proceso contra service methodology.", "proceso contra policies methodology.", "proceso contra mexico methodology.", "proceso control devices methodology.", "proceso contra civiles 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 statistical methodology.\") OR (\"proceso contra devices methodology.\"))~".
• Removing quotes may allow a broader search: (( process control statistical methodology. ) OR ( proceso contra devices methodology. ))~.
• Adding a wildcard symbol may retrieve word variants: (("process control statistical methodology.") OR ("proceso contra devices methodology."))*.
