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