Perhaps you should try some spelling variations:
"john running space" » "john running apache", "john running state", "john running spark", "john dunning space", "john hanning space", "down running space"
"john dennis speke" » "john dennis dieks", "john dennis epple", "john dennis duke", "john denne speke", "john cennick speke"

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: (("john dennis speke") OR ("john running space")).
• Removing quotes may allow a broader search: (( john dennis speke ) or ( john running space )).
• Adding a wildcard symbol may retrieve word variants: (("john dennis speke") or ("john running space"))*.
