Query Expressions

In addition to simple search terms, WorldWideScience can conduct searches using multiple search terms, Boolean operators, exact phrases, parentheses, and wildcards.

Note: Searches are not case-sensitive. A search for SCIENCE, Science, or science will return the same results.  

Multiple Search Terms

Multiple terms can be searched, using the Boolean AND by default.

Example: A search for science technology will return results on both science and technology.

Boolean Operators

WorldWideScience recognizes the operators AND, OR, and NOT

  • Example: A search for science AND technology will return results on both science and technology.
  • Example: A search for science OR technology will return results on either science or technology.
  • Example: A search for science NOT technology will return results on science but not technology.

Exact Phrases

Phrases contained in double quotations (“ ”) will be searched as an exact phrase.

Example: A search for “nuclear energy” will return only those results where energy immediately follows the term nuclear.


Using parentheses allows control over the order in which Boolean expressions are evaluated.

Example:  A search for nuclear ((energy consumption) OR waste) will return results for either nuclear energy consumption or nuclear waste.

Example: A search for ((black holes) or (dark matter)) AND gravitation will search for either black and holes and gravitation or dark and matter and gravitation.


Wildcards (* and ?) allow a search term to act as a “root” for words with different forms.

Example: A search for part* will return results that include the terms part, particle, participate, etc.

Example: A search for part? will return results with only one additional character: parts, party, etc.


Obtaining Full-Text Documents in

Approximately 95 databases and portals from over 70 countries are currently searchable through the global science gateway. Many of these sources offer access to full-text documents referenced in their bibliographic records. Detailed information regarding individual database and portal full text access options is available from the source websites. These sources are listed on the Advanced Search page. Links to these sources can also be found in the search results citations. Additional information regarding full text access is provided below. 

Full Text Availability

Sources having full text access for viewing, printing, or downloading should have "Full Text Available" displayed in their search results citations. These full-text sources will additionally have their name listed under the "Full Text Available" section in the "Topics" tab in the left menu on the search results pages.

Some of these sources may additionally provide icons for linking to the full text in their citations. To view an electronic full-text document, click on the full-text icon in the advanced search results record if an icon is displayed. (You must have Adobe Acrobat Reader plug-in installed to read PDF records.) To download an electronic document, right-click on the icon and choose "Save Link As" or "Save Target As". The download time depends on the size of the document and the technical capabilities of your equipment. If there is no full-text icon, go to the Source's bibliographic record by clicking on the title for further information.

Unrestricted Full Text

Much of the full text provided by sources is freely available and in the open domain.

Restricted Access to Full Text

A few of the sources require that users be registered, or have specific domains, to access their full-text collections. Users should refer to the source’s bibliographic records or websites for terms of access.

Journal Articles

Some of the sources provide search results from Journal publishers. If the full text is a copyrighted journal article, it may be available for purchase from the publisher's website. Alternatively, many institutions, universities, and corporations maintain journal subscriptions for their library patrons. Detailed information regarding access should be available from the source website or via the publisher's website.

Open Access Journals

Open Access journals are defined as journals that use a funding model that does not charge readers or their institutions for access to full text documents. Users may obtain access to full-text articles from Open Access journals for free. Open Access journal articles made available by sources should be marked appropriately.

Full Text access via Interlibrary Loan

Some of the sources provide access to their full-text documents through interlibrary loan programs where users can borrow books or receive photocopies or files that are owned by another library. These source websites will provide detailed information regarding the process.

Bibliographic-only Sources

Some of the sources provide results from bibliographic-only databases.  Bibliographic records from these sources displayed in search results will not offer full text access. It may be possible, however, to locate the full text item through another library or through a document delivery service.

On behalf of the WorldWideScience Alliance, the Office of Scientific and Technical Information (OSTI) continues to work with Database Participants to increase access to their full-text information. We anticipate that this full-text collection will grow over time.
