Perhaps you should try some spelling variations:
"particles interconnection" » "parallel interconnection", "particles interaction", "particles introduction"
"partial interconnections" » "mail interconnections", "optimal interconnections", "social interconnections", "vertical interconnections", "spiritual interconnections", "parallel interconnections"
"optical interconnections" » "optical interconnects", "optical interactions"
"partial interconnection" » "vertical interconnection", "spiritual interconnection", "parallel 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 ("optical interconnections"))) OR ("particles interconnection"))) OR ("partial interconnection")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"partial interconnections\") OR (\"optical interconnections\"))) or (\"particles interconnection\"))) or (\"partial interconnection\"))".
• Removing quotes may allow a broader search: (((((( partial interconnections ) OR ( optical interconnections ))) or ( particles interconnection ))) or ( partial interconnection )).
• Adding a wildcard symbol may retrieve word variants: (((((("partial interconnections") OR ("optical interconnections"))) or ("particles interconnection"))) or ("partial interconnection"))*.
