Mercado Software Inc. announced it has released its Enterprise Search & Navigation (ESN) solution. Designed from the ground up for a web services enterprise architecture, ESN provides a solution for locating information scattered across multiple information repositories and stored in disparate data formats. ESN provides a single point of information access for users to explore all organizational information, whether it is structured, semi-structured, or unstructured content. ESN utilizes linguistic tools and hierarchical indexing that uses structure in addition to text to optimize relevancy ranking for all content types. ESN’s modular architecture is adaptive to existing systems and new data sources and is customizable. Its XML and SOAP architecture simplifies integration and maintenance. The solution is scalable to any data volume and user load, and features a quick update capability that helps keep search indices fresh.
