Discovery Tools vs. Metasearch: What is the Difference?

Libraries use discovery tools and metasearch to create a “one-stop” search experience for their users, but the two work in different ways.

Discovery tools collect and index full-text data and its metadata in one place, which is what users are searching when they search in one of these tools.

We regularly send both our content and our metadata to these discovery tool vendors:

Metasearch and Credo

Federated search, or metasearch, is when a user enters a search term that goes out to several different databases; all those results then appear in the same place and users can navigate to them from there.

For customers using the metasearch options listed below, we can provide a unique IP address or a z39.50 username and password so that Credo results are included in their metasearch results:

360 Search (Serials Solutions)

AGent Search (Auto-Graphics)

EBSCOhost Integrated Search (EBSCO)

Encore Synergy (Innovative Interfaces/III)

Explorit (Deep Web Technologies)

Metalib (Ex Libris)

Reference Universe (Paratext)

Research Pro (Innovative Interfaces/III)
