Perhaps you should try some spelling variations:
22weak interaction » weak interactions, wear interaction, work interaction
werk interactions » weak interactions, work interactions, work interaction
weak interaction » weak 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: %((((22weak interaction) OR (weak interaction))) OR (werk interactions))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((((22weak interaction) OR (weak interaction))) or (werk interactions))%22".
• Adding a wildcard symbol may retrieve word variants: %((((22weak interaction) OR (weak interaction))) or (werk interactions))%22*.
