NSDL: NCore Platform

Services:Overview - Spines of CD covers

Services: Search

The NCore Search Service allows users to search for and find resources in a digital library. Search queries can access Dublin Core metadata stored in the NSDL Data Repository (or another NCore repository), or the text content of the resource web pages. The Search Service is based on the Lucene search engine and Nutch web search software.

The NCore search service supports scalable searching over millions of records and currently handles approximately five million queries per month at NSDL.org.
