Perhaps you should try some spelling variations:
"summarily executed" » "summary executed", "summarium executed", "summarily executes", "summarily executif", "summarily exerted", "summarily executesd", "summarily executived", "summarily executifd"
"summarily executives" » "summary executives", "summarium executives", "summarily executive", "summarily ejecutivos", "summarily executivo"
"summarize execute" » "summarizes execute", "summarized execute", "summarium execute", "summarize executes", "summarize executive", "summarize 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: "((((\"summarily executed\") OR (\"summarize execute\"))) OR (\"summarily executives\"))~".
• Removing quotes may allow a broader search: (((( summarily executed ) OR ( summarize execute ))) OR ( summarily executives ))~.
• Adding a wildcard symbol may retrieve word variants: (((("summarily executed") OR ("summarize execute"))) OR ("summarily executives"))*.
