I need a work-around code solution to enact search term highlighting

I am using ?Robohelp for Framemaker? to create my Webhelp. This is a terrific program except for two problems, one, it is now obsolete, and two, it does not highlight search criteria in the search results. I do not have the money to purchase a new program; what I?d like to do at this point is just get my reliable Robohelp for Framemaker to highlight the search words found. Is there a work-around solution where I might insert some kind of java script or html code that will get the search words to highlight?
