Perhaps you should try some spelling variations:
"summarily executed" » "summary executed", "summarium executed", "summarily executes", "summarily exerted", "summarily executesd", "summarily executived"
"summarily execute" » "summary execute", "summarium execute", "summarily executes", "summarily executive"
"summarize executif" » "summarizes executif", "summarized executif", "summarium executif", "summarize executive", "summarize execution", "summarize executivo"

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: "((\"summarily executed\") OR (((\"summarily execute\") OR (\"summarize executif\"))))~".
• Removing quotes may allow a broader search: (( summarily executed ) OR ((( summarily execute ) OR ( summarize executif ))))~.
• Adding a wildcard symbol may retrieve word variants: (("summarily executed") OR ((("summarily execute") OR ("summarize executif"))))*.
