This is very easy:
Imaging your template:

<div class="col1"><!-- Column 1 start -->
<!--NO_PRINT_END//--><!--SEARCH_HIGHLIGHT_START//-->
{CONTENT_ABOVE}{BACK_BUTTON}{CONTENT}{CONTENT_BELOW}
<!--SEARCH_HIGHLIGHT_END//--><!--NO_PRINT_START//-->
</div>

Now you will get the search results highlighted even within the resulting pages - WOW - and not at the results page itself only
