Perhaps you should try some spelling variations:
"proceso contra statistics methodology." » "proceso contra semiotics methodology.", "proceso contra linguistics methodology.", "proceso century statistics methodology.", "process control statistics methodology."
"proceso control statistical methods." » "process control statistical methods.", "proceso contralos statistical methods.", "proces contre statistical methods.", "proceso control estadisticas 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: "((\"proceso contra statistics methodology.\") OR (\"proceso control statistical methods.\"))~".
• Removing quotes may allow a broader search: (( proceso contra statistics methodology. ) OR ( proceso control statistical methods. ))~.
• Adding a wildcard symbol may retrieve word variants: (("proceso contra statistics methodology.") OR ("proceso control statistical methods."))*.
