Search

E-prints on Web Sites search – The E-print Network Search searches indexed PDF documents residing on e-print Web sites. This search has been optimized to reduce the "noise" of irrelevant items and to minimize duplication.

Database search – The deep Web search offers full-text searching within and across database collections. This provides users the capability to pulse the search engines of selected e-print databases with a single query. A compiled search results list is returned. If a description is needed for a database, please refer to the Collection Description page.

The results of an E-print Network search may include full-text, bibliographic citations and other types of material. The searches are powered by Distributed Explorit from Deep Web Technologies. [exit federal site]

Search Tips

Although resources may employ different options, the following are generally true for E-print Network searching:

Where Supported Note

Some collection search engines may not support field searching in some fields such as creator/author, title, and/or date.  However, users may enter search terms in these fields and the E-print Network's federated search attempts the search by performing a search on the collection in the most applicable field available.  For instance, if a collection does not support searching for an author/creator, the E-print Network's federated search may search that collection's full bibliographic record for the entered author's name.

About the Search Engine

Distributed Explorit and Explorit Focused Crawler

Explorit is the core product from which all other current Deep Web Technologies products are derived. Basically, Explorit is a highly configurable and easily customizable interface to commercially available, off-the-shelf (COTS) full-text search engines from Lextek International and Verity. Explorit provides the capability to deploy small to large-scale collections of information on the Web – fully searchable and easily navigable – to a wide range of user communities. Large organizations or information purveyors with many collections of heterogeneous information benefit from the consistency and usability of the Explorit user interface: whether they deploy one collection or one hundred, users quickly learn that all Explorit applications operate essentially the same way, and variances are determined by content rather than inconsistent design.

Registering

Alerts can be set up for any combination of the collections represented on the "Search" page. These collections currently include reports on computer science, mathematics, and physics.  To create a User Name and Password, follow these steps:

  1. Select NEW PATRON to register as a new user.
  2. Complete the Registration Form to create a user name and password.
  3. Click Register then click Login.

  6. If you have forgotten your password, find an email message sent to you from eprints_help@osti.gov, there will be a URL listed in the email. Click on or paste the entire URL into your browser location input box and press enter. Your page allowing you to view and edit your alerts will be shown. You can then change your password by selecting the Change Password button at the bottom of the page.
  7. If you have forgotten your password and can't find an email with the URL for your alerts, send an email to eprints_help@osti.gov. We will provide you with the information to get to your individual account and create a new password.

Creating Your Search

  1. In the Alert Name provide the unique title of what you want your search to be called. You'll need the alert name to change or delete the alert or to view results.
  2. Enter the search term(s) you want included in this profile in the Full Record field. (You may wish to use the Search page to determine the best keywords and collections prior to creating your alert).
  3. Select the number of records to retrieve from each collection. This can be in increments of 10, 25, 50, or 100.
  4. Check the boxes of the e-print collections that you want your alert run against weekly (Please realize we have no control of how often these servers are updated so you may get zero results back with some servers).
  5. Click the submit button. This will complete the alert set up and it will be run with the next weekly batch process.
