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