Perhaps you should try some spelling variations:
22weak interaction » weak interaction, weak interactions, work interaction
wear interaction » weak interaction, near interaction, weak interactions
ear interaction » near interaction, ar interaction, par interaction

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