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