Solr Clustering Issue

[Joseph Obernberger]

Hi - I'm using carrot2 inside of solr cloud and have noticed that 
queries that involve parenthesis don't seem to work correctly.  For 
example if I have:
q=Field1:(term1 OR term2) AND Field2:(item1 OR item2)
The clustering seems to ignore the values in parenthesis.  If instead I do:
q=(Field1:term1 OR Field1:term2) AND (Field2:item1 OR Field2:item2)
this works as expected.  Anyone else having this issue?  Apart from 
re-writing the cluster query, I'm not sure of a solution.

Thank you!
