"Law Offices have been at the forefront of the Enterprise Search market." is the first sentence in an article about the evolution of enterprise search at the 450 attorney firm, Bracewell & Guilanai LLP -- Third Time a Charm for Law Firm, Network Computing, 10/16/2009.
Law firms at the forefront? Really? I'm not sure I'm buying that as a blanket statements, but it does seem to apply to Bracewell. According to the article, they started out 20 years ago with Open Text, then moved to Autonomy, and are now happily searching using Recommind. That's an impressive history of search engine implementation and evolution.
