I bought the plugin and it does return profiles that match on the selected fields like I want.
Problem is some profile names have an ampersand "&" which comes out in the results as (no quotes) "&"
double quotes don't show up right either, maybe all escapable characters are problem?
Joomla articles that match search terms appear normal, so I can only assume it is the Joomla 2.5 CB Search Plugin causing the problem.
