Perhaps you should try some spelling variations:
"lethal injection" » "lethal infection", "metal injection", "ethanol injection"
"method detection" » "methods detection", "method selection", "method section"
"metal detection" » "metal detector", "seal detection", "viral detection"

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (("lethal injection") OR ((("metal detection") OR ("method detection")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"lethal injection\") or (((\"metal detection\") OR (\"method detection\"))))".
• Removing quotes may allow a broader search: (( lethal injection ) or ((( metal detection ) OR ( method detection )))).
• Adding a wildcard symbol may retrieve word variants: (("lethal injection") or ((("metal detection") OR ("method detection"))))*.
