How can I list the title of a document in a search?

We have crawled existing intranet and websites and successfully classified the pages and documents using Trex.

In the search results we're getting lots of documents returned but they are listed by filename. As most of the documents are PDF or word .doc files which have their own Title and Summary properties we want to import these into the CM properties and display these in the search results instead.

Anyone have any ideas on how to do this?

Thanks,
