Enterprise Search and Retrieval (ESR) tools enable users to discover the most appropriate information from multiple information sources and repositories. The ability to aggregate information from across all of the corporate repositories through a single search, enables users to deliver a comprehensive view of all interactions with a customer, citizen, or business partner about a product or piece of news, or about all the activity related to a business process. This means that not only can better decisions be taken, but also that they can be taken faster, with less risk. This has a real impact for organisations across a range of industry sectors that have to be able to discover information speedily to address the requirements of compliance with a growing number of regulations and legislation.
