Perhaps you should try some spelling variations:
"summarily executed" » "summary executed", "summarium executed", "summarize executed", "summarily executif", "summarily exerted", "summarily executived", "summarily executifd"
"summarily execute" » "summary execute", "summarium execute", "summarize execute", "summarily executive", "summarily executif"
"summarily executes" » "summary executes", "summarium executes", "summarize executes", "summarily executives", "summarily executifs", "summarily executors", "summarily executif"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("summarily executed") OR ("summarily execute"))) OR ("summarily executes"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"summarily executed\") OR (\"summarily execute\"))) OR (\"summarily executes\"))".
• Removing quotes may allow a broader search: (((( summarily executed ) OR ( summarily execute ))) OR ( summarily executes )).
• Adding a wildcard symbol may retrieve word variants: (((("summarily executed") OR ("summarily execute"))) OR ("summarily executes"))*.
