Perhaps you should try some spelling variations:
"method detection" » "methods detection", "method selection", "method section"
"metal injection" » "metal interaction", "cell injection", "well injection"
"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: (("metal injection") OR ((("metal detection") OR ("method detection")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"metal injection\") or (((\"metal detection\") OR (\"method detection\"))))".
• Removing quotes may allow a broader search: (( metal injection ) or ((( metal detection ) OR ( method detection )))).
• Adding a wildcard symbol may retrieve word variants: (("metal injection") or ((("metal detection") OR ("method detection"))))*.
