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.
Example: science technology
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.
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.
Databases and portals from over 70 countries are currently searchable through the WorldWideScience.org global science gateway. Many of these sources offer access to the full text documents referenced in their bibliographic records. Detailed information regarding full text access 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. Additional information regarding full text access is provided below.
