Perhaps you should try some spelling variations:
22weak interaction » weak interaction, work interaction, weak integration
wear interaction » weak interaction, ear interaction, near interaction
22weak » 22werk
weak » werk

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