Perhaps you should try some spelling variations:
"procesal control statistics methods." » "procesal control statistical methods.", "procesal control estadistico methods.", "procesal control estadistica methods.", "procesal control statistics methodology.", "process control statistics methods.", "social control statistics methods.", "proces contre statistics methods."
"proceso contra statistics methods." » "proceso contra statistical methods.", "proceso contra statistics methodology.", "proceso century statistics methods.", "proceso control statistical methods.", "process control statistics methods."

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: "((\"procesal control statistics methods.\") OR (\"proceso contra statistics methods.\"))~".
• Removing quotes may allow a broader search: (( procesal control statistics methods. ) OR ( proceso contra statistics methods. ))~.
• Adding a wildcard symbol may retrieve word variants: (("procesal control statistics methods.") OR ("proceso contra statistics methods."))*.
