Hi Vivek,
I understand, but that feature only works with the live results – the plugin cannot push that to the results page unfortunately.
You might still be able to access the original “live search” fields via the get_asp_result_field function via the results loop.
In this case, replacing probably the the_excerpt(); or equivalent function call within the search.php template file (or within the loaded template part) in the theme directory with the_asp_result_field('content');
