Perhaps you should try some spelling variations:
"particles interconnection" » "partial interconnection", "parallel interconnection", "particles interaction"
"partial interconnections" » "partial interconnection", "mail interconnections", "optimal interconnections"
"optical interconnections" » "optical interconnects", "optical interactions"

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