VHL Integrated Search

The VHL Integrated Search Engine (iAHx) streamlines information retrieval through a unified interface, enhancing user experience by minimizing the steps required to access diverse information sources. Unlike traditional search engines that demand navigating multiple formats and interfaces, iAHx enables users to explore clusters of organized documents, refine search results, and export outcomes in various formats, including XML and RSS. This innovative system addresses challenges like maintenance costs and offers personalized services, ultimately reducing the learning curve for users.
