Advanced Search

Scirus Advanced Search offers you the ability to search on more specific fields. To begin, enter your keywords and specify in which fields you want that query to search:

•	The complete document
•	Article title
•	Journal title
•	Author name(s)
•	Author affiliation(s)
•	Keyword(s)

•	(Part of a) URL

Then, narrow your search further by selecting one of the following options from the pull-down box to the left of the search bar:

•	Any of the words - your search results will contain one or more of the keywords you entered in the search box
•	Exact phrase - your search results will contain the exact phrase you entered

You can then combine two search queries by linking them with the terms AND, OR, ANDNOT from the drop-down list.
