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