Lawyers and other legal professionals will have a new resource for online information gathering with WestlawNext, an updated search engine that, the company says, "offers a clean, modern interface and powerful new search functionality that makes legal professionals significantly more efficient and gives them the confidence that they’ve explored every relevant document."

WestlawNext is powered by a proprietary search engine technology called WestSearch. WestSearch incorporates techniques that mirror those used by human legal researchers to discover important documents, and adds sophisticated search engine automation to the process to make searches happen quickly, either by Boolean or descriptive queries.

Thomson Reuters president and CEO Peter Warwick said that "we’ve combined our 138-year legacy of analyzing and organizing legal information with cutting edge search technology to set a new standard for legal research tools."

Search engine optimization (SEO) for legal research is very different from the standard model of SEO, since there are fewer entries competing for places on the list, but the goal is the same: to provide the most relevant search results to any given query.
