Search result pages and destination pages serve completely different purposes, and you can't apply the same UI to both. If you ran a restaurant, you might decide to laminate the menus, but I hope you wouldn't laminate the entrees, too.
Highlighting "salmon" menu entries on web site could make sense for the user who is searching for "salmon", wouldn't it?
But let's be more specific: I run a job board (PostJobFree) and recruiters frequently find resumes on Goolge in queries like this:
http://www.google.com/search?q=intitle%3Aresume+sharepoint+C...
If you open first result - you can see how these keywords are highlighted. I'm pretty sure that this highlighting is a convenient feature for recruiters who want to quickly scan resume.
