Perhaps you should try some spelling variations:
"proceso contra statistical methodology." » "proceso contra statistics methodology.", "proceso contra statistical methods.", "proceso control statistical methodology.", "process control statistical methodology."
"procesos contables science methodology." » "procesos contables sciences meteorology.", "procesos contables science anthropology.", "procesos sociales science methodology.", "procesos penales science 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: "((\"proceso contra statistical methodology.\") OR (\"procesos contables science methodology.\"))~".
• Removing quotes may allow a broader search: (( proceso contra statistical methodology. ) OR ( procesos contables science methodology. ))~.
• Adding a wildcard symbol may retrieve word variants: (("proceso contra statistical methodology.") OR ("procesos contables science methodology."))*.
