As the story explains,
The new search tool is an open source implementation of several applications used in the Library, Archive, and Museum communities, including Apache Solr for faceted searching. The tool enables users to interact with the ANS collection through keyword searches or by browsing and sorting on numerous categorical and physical attributes common to numismatics. This search tool connects individual objects together by these searchable attributes, allowing users to seamlessly navigate from one object to its relations.
