MultiSearch — new federated, deep web database for Defence

US DTIC Online portal deploys Deep Web Technologies’ MultiSearch interface23 Oct 2008

Search solutions provider Deep Web Technologies, US, has launched an updated interface for the Defense Technical Information Center’s new DTIC Online research portal ( DTIC is part of the US’ Department of Defense (DOD). The interface, known as MultiSearch, offers four defence search channels from a single drop-down menu, allowing users to access a collection of scientific and defence-related resources in one simultaneous search. The search employs the latest version of Deep Web Technologies’ Explorit Research Accelerator, which is seen to provide ‘smart’ clustering, encyclopedia sidebars from Wikipedia, and EurekAlert! science news.

DTIC supports the DOD and its community by centralising scientific, technical and related defence-information services, databases and systems. Its new DTIC Online significantly expands the breadth of information scanned and retrieved with its four search channels: DOD websites, DTIC Public Scientific and Technical Information, the DTIC Website, and Federal Scientific and Technical Information. MultiSearch also includes a federated search of other federated search websites, including and – both powered by the Explorit Research Accelerator. It therefore is projected to consolidate a number of advanced search engines within one search, delivering results users might never have uncovered.

The upgraded MultiSearch portal adds new features that seek to enrich the user experience and value of research. By taking advantage of Explorit’s ‘smart clustering,’ MultiSearch provides relevance-ranked clusters that allow users to see their results organised by topic. It also retrieves and displays entries from Wikipedia and EurekAlert! that complement the search experience. Explorit delivers not only relevant results, but pathways and context to guide users to more relevant search results.

Deep Web’s federated search technology is projected to enable fee-based or proprietary content to be searched publicly on the Internet, without giving it away. This content is not searchable by public search engines such as Google and Yahoo.

DTIC Online was created specifically for the defence community. MultiSearch can be accessed from the pull-down menu by selecting ‘Federal S&T’ or by going directly to ( search is free and much of the content is available at no cost. Some content – like that accessed through Scitopia – can be purchased on a pay-per-view basis or accessed by a subscription.

One thought on “MultiSearch — new federated, deep web database for Defence

  1. DTIC employs a number of applications to widely disseminate the results of DoD public release scientific, technical and medical research. Its Technical Reports collection was part of the “deep web” until DTIC implemented the Open Archives Initiative (OAI) protocol in early 2006. OAI allows third party harvesters easy access to DTIC’s content in a variety of formats such as COSATI, MARC, Dublin Core (DC) and HTML using XML technology with links to the digital content using DTIC’s Handle Service . Today DTIC offers free online access to more than 343,000 full-text documents and 1,109,000 citations. This number grows as DTIC adds new documents and digitizes its legacy collection. However, search engines are under no obligation to index this content and many do not. And of those that do, no ranking preference is given to the free government source.
