BA Insight is showing enterprise search for SharePoint, and visual enhancements – such as document preview, federated search, graphic refiners, and content integration from over 30 systems (Lotus Notes, Worksite, Zantaz, SAP, and Salesforce, among others).

In terms of searching within documents, you can preview the document … and search within it. So if the document is large, you don’t have to download the whole document to see what you are looking for.

BA also allows you to create search-based applications. Eg., in a legal firm, you can examine a matter code, to find specific expertise. You would see all of the lawyers that had worked on the matter – and being able to connect with them. You can link off to the profile for the person.
