Perhaps you should try some spelling variations:
summarize » summarizes, summarized, summarium
executived » executivo, executed, executiva, ejecutivad, ejecutivod
esecutive » ejecutiva, ejecutivo, executivo
executive » ejecutiva, ejecutivo
executives » ejecutivas, ejecutivos
execute » executed, executes, executif

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: "(( summarize (executived OR esecutive) ) OR ( summarize ((executive OR executives) OR execute) ))~".
• Adding a wildcard symbol may retrieve word variants: (( summarize (executived OR esecutive) ) OR ( summarize ((executive OR executives) OR execute) ))*.
