Perhaps you should try some spelling variations:
"procesos control statistical methodology." » "procesos control statistics methodology.", "procesos control statistical methods.", "proceso contra statistical methodology.", "procesos contables statistical methodology.", "proceso contralos statistical methodology."
"process control estadistica methods." » "process control estadistico methods.", "process economia estadistica methods.", "process control estadisticas metodos.", "process control statistical methods.", "process control estadisticas medicas."

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 statistical methodology.\") OR (\"process control estadistica methods.\"))~".
• Removing quotes may allow a broader search: (( procesos control statistical methodology. ) OR ( process control estadistica methods. ))~.
• Adding a wildcard symbol may retrieve word variants: (("procesos control statistical methodology.") OR ("process control estadistica methods."))*.
