Perhaps you should try some spelling variations:
"boundary revisited network" » "bounding revisited network", "boundary assisted network", "body revisited network", "boundary revisited work", "boundary revisiting networks", "boundary envisioned network"
"boundary invisible network" » "boundary initial network", "boundaries visible network", "abundantly invisible network", "boundary visible network", "boundary invertible network", "boundary invisible work"

Try widening your search to All Fields.

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: (("boundary revisited network") OR ("boundary invisible network")).
• Removing quotes may allow a broader search: (( boundary revisited network ) or ( boundary invisible network )).
• Adding a wildcard symbol may retrieve word variants: (("boundary revisited network") or ("boundary invisible network"))*.
