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