On the first day of Defrag, I stopped by to chat with Brian Cheek, Director of Business Development for TigerLogic, about his firm's product Yolink, which is a next-generation technology that enhances search by extracting information from behind links and inside of documents.  Yolink-graphic I was amazed I hadn't heard about Yolink until a few days prior to Defrag, and found it pretty amazing as I started to play with it.  See the following coverage for more about this technology: Yolink Helps Web Researchers Search Behind Links (Mashable) … Yolink's Next Step Search Pulls Info from Behind Links and Inside Docs (ReadWriteWeb) … and Yolink – A Search Accelerator for Deep Internet Research (MakeUseOf.com).

It's available as a plugin for all the major browsers. It's also available as a desktop app for Windows PC users. You can even get a Yolink widget for your site or blog (again, all the major platforms). Also be sure to look at some cool lab experiments created by Yolink engineers that showcase the use of the Yolink API. The API allows integrating Yolink into any web service. It can be used to enhance existing search engine results, or to provide site or app search functionality outright. The API is simple to implement and completely customizable.
