Perhaps you should try some spelling variations:
"systems analyst" » "systems analysis", "systems analytic", "system analysis"
"system analyses" » "system analysis", "ecosystem analysis", "system analyzing", "system analysiss", "system analyzings"
"system analyse" » "system analysis", "system analyzing"

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: (("systems analyst") OR ((("system analyse") OR ("system analyses")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"systems analyst\") or (((\"system analyse\") OR (\"system analyses\"))))".
• Removing quotes may allow a broader search: (( systems analyst ) or ((( system analyse ) OR ( system analyses )))).
• Adding a wildcard symbol may retrieve word variants: (("systems analyst") or ((("system analyse") OR ("system analyses"))))*.
