Perhaps you should try some spelling variations:
"procesos contables estadistico methods." » "procesos control estadistico methods.", "procesos control estadistica methods.", "procesos hoteles estadistica methods.", "procesos contables estadisticas metodos.", "procesos sociales estadistico methods.", "procesos penales estadistico methods."
"process control statistical methods." » "proceso control statistical methods.", "procesal control statistical methods.", "process control statistics methods.", "process 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: "((\"process control statistical methods.\") OR (\"procesos contables estadistico methods.\"))~".
• Removing quotes may allow a broader search: (( process control statistical methods. ) OR ( procesos contables estadistico methods. ))~.
• Adding a wildcard symbol may retrieve word variants: (("process control statistical methods.") OR ("procesos contables estadistico methods."))*.
