Perhaps you should try some spelling variations:
"help a reports test" » "help a reports best", "help a report test", "help a reports text", "help a report's test", "help _ reports test", "help 2 reports test"
"help a report stem" » "help a report step", "help a report item", "help a report system", "help _ report stem"

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: (("help a report stem") OR ("help a reports test")).
• Removing quotes may allow a broader search: (( help a report stem ) or ( help a reports test )).
• Adding a wildcard symbol may retrieve word variants: (("help a report stem") or ("help a reports test"))*.
