Perhaps you should try some spelling variations:
"functions analysis" » "functional analysis", "equations analysis"
"solutions analysis" » "resolution analysis", "evolutionary analysis"
"function analysis" » "functional analysis"

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: (("functions analysis") OR ((("function analysis") OR ("solutions analysis")))).
• Removing quotes may allow a broader search: (( functions analysis ) or ((( function analysis ) or ( solutions analysis )))).
• Adding a wildcard symbol may retrieve word variants: (("functions analysis") or ((("function analysis") or ("solutions analysis"))))*.
