Hi Tim,
I’m afraid this is not related to the plugin, as it should not have any effect on the results page layout. Many themes display the post excerpts within the results pages, not the full content, and often the excerpts are stripped from additional html tags. I suggest checking the search.php file in the theme directory to see how exactly it is processed. There might be options as well somewhere in the theme settings that may let you change the search results display, I am not sure.
