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