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