Introduction

The Institute of Electrical and Electronics Engineers (IEEE) maintains the IEEE Xplore digital library. IEEE Xplore contains a comprehensive collection of full text documents in electrical engineering, computer science, and electronics journals.

Access to IEEE Xplore is available to individual IEEE members and to subscribing institutions. Guests may search and access abstracts free of charge. Publications of interest are available for purchase to guests.

Major Recent Updates

March 2011

The Institute of Electrical and Electronics Engineers (IEEE) collaborated with Access Innovations, Inc. to complete a comprehensive re-indexing of about 2.1 million IEEE article records in the IEEE Xplore Digital Library database.[1]

Operators

According to the IEEE Xplore help files:

"Search operators are elements that express relationships between search terms or search expressions, or that otherwise modify a query. In structured advanced searching, you can use the logical operators AND, OR, and NOT. In command searching, you can use these operators plus NEAR (for unordered proximity searches) and ONEAR (for ordered proximity searches), as described here."


Operator

Syntax

Find Results That...

AND

x AND y

Match both expressions x and y

OR

x OR y

Match either expression x or y or both

NOT

NOT x

Do not match expression x

x NOT y

Match expression x but not y

NEAR

x NEAR/# y

Match expression x within # words of y (<strong>x can appear before or after y) </strong>

ONEAR

x ONEAR/# y

Match expression x before and within # words of y

Additional facts regarding operators include:[2]

  • There is no limit to the number of proximity operators in a ten-term query.
  • IEEE Xplore does not support using * wildcards with proximity operators.
  • The limit is one term or a phrase in quotation marks on either side of the NEAR operator.

Truncation

According to the IEEE Xplore help files: "To search for words that have spelling variations or contain a specified pattern of characters, use * (called a wildcard character) to represent the variations. The * wildcard represents zero, one, or multiple alphanumeric characters in the position it occupies."

Please note that IEEE Xplore supports right-hand and internal truncation, but does not support left-hand (also known as leading) truncation.

Additional facts regarding truncation include:[2]

  • You may not used a * wildcard within double quotation marks.
  • To narrow your search, you can use a * wildcard in the SEARCH WITHIN RESULTS box above the facets.
  • You may only use four terms with * wildcards per search. However, you can use an additional one if refining your initial search set by using the SEARCH WITHIN RESULTS box on the left side, above the facets.


Stemming

According to the IEEE XPlore help files: "IEEE Xplore looks for plural forms of any keywords entered. For example, if you enter computer, IEEE Xplore also finds computers.

In addition, IEEE Xplore looks for verb forms of keywords as well as British and American English equivalents. For example:


If you enter…

IEEE Xplore also finds…

run

run, running, etc.

ignite

ignite, ignited, igniting, etc.

oscillate

oscillate, oscillated, oscillating, etc.

carburettor butterfly

carburetor butterfly

fibre

fiber


Notes

Other important search tips for IEEE Xplore include:[2]

  • Authors' names are not standardized, so users should search for all possible variations. Users can also utilize the author facet on the left side of the search results page to narrow results.
  • Words within phrases are counted separately, not as one word.
  • Hyphens are ignored. Therefore, a hyphenated word or phrase is interpreted as an integrated, single term.
  • The limit to the number of terms per search string is ten terms.
  • If an article has been made available in IEE Xplore via Early Access, a "Date of Publication" will be shown as evidence of the exact date the article was first made publicly available.

The IEEE Xplore digital library may also be searched at Scitopia.org.
