Perhaps you should try some spelling variations:
"functions analysis" » "functional analysis"
"solutions analysis" » "resolution 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: (("function analysis") OR ((((("functions analysis") OR ("solutions analysis"))) OR ((("equations analysis") OR ("evolutionary analysis")))))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"function analysis\") or (((((\"functions analysis\") OR (\"solutions analysis\"))) or (((\"equations analysis\") or (\"evolutionary analysis\"))))))".
• Removing quotes may allow a broader search: (( function analysis ) or ((((( functions analysis ) OR ( solutions analysis ))) or ((( equations analysis ) or ( evolutionary analysis )))))).
• Adding a wildcard symbol may retrieve word variants: (("function analysis") or ((((("functions analysis") OR ("solutions analysis"))) or ((("equations analysis") or ("evolutionary analysis"))))))*.
