If you have defined a search that results in few or no documents matching your search criteria, you can broaden your search so that it finds more matches. Try these techniques:
· Add an alternative search term to your original specification, using the Or operator. (See Specifying Multiple Criteria.)
· Use truncation and the "*" wildcard character to specify additional variations of a search term.
Example: To find documents about MOS, CMOS, and BiCMOS, you can specify
*MOS
IEEE Xplore® returns all matches with words that end in MOS.
· Use the "?" wildcard character to specify a single unknown or varying character in your search term.
Example: Suppose you know that someone named Gardner or Gartner wrote an article about the use of robots. You can specify robots for the subject term, and for the author you can specify
Gar?ner
IEEE Xplore® returns all documents about robots written by either Gardner or Gartner.
