Perhaps you should try some spelling variations:
"spiritual interconnection" » "optical interconnection", "digital interconnections", "optimal interconnection"
"partial interconnections" » "particles interconnection", "optical interconnections", "mail interconnections", "particles interconnections", "parallel interconnections", "physical interconnections"
"vertical interconnection" » "optical interconnection", "vertical interconnects", "electrical interconnection"
"partial interconnection" » "particles interconnection", "parallel interconnection", "physical interconnection"

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: (("partial interconnections") OR ((((("partial interconnection") OR ("vertical interconnection"))) OR ("spiritual interconnection")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"partial interconnections\") or (((((\"partial interconnection\") OR (\"vertical interconnection\"))) or (\"spiritual interconnection\"))))".
• Removing quotes may allow a broader search: (( partial interconnections ) or ((((( partial interconnection ) OR ( vertical interconnection ))) or ( spiritual interconnection )))).
• Adding a wildcard symbol may retrieve word variants: (("partial interconnections") or ((((("partial interconnection") OR ("vertical interconnection"))) or ("spiritual interconnection"))))*.
