What advanced search options does OPEN FAU support?

The OPEN FAU search function (magnifying glass icon or https://open.fau.de/search) allows you to perform complex searches..

By default, a Boolean “AND” search is performed when multiple terms are entered (see the Wikipedia entry on Boolean algebra). This will return results that include each of the terms. “OR and NOT searches are also possible. For example, searching for “medical NOT care” will return results containing “medical” but not “care.”

Phrase searches, such as “medical care” (in quotation marks), return results containing the exact term.

Time range searches are also possible, for example dc.date.issued:[2007 TO 2022] or dc.date.issued:[2012 TO *].

The latter is a wildcard search. The wildcard character * can be used.

Certain metadata fields can be addressed by their Dublin Core element names. For example, a search for “dc.title:medical” returns results where the dc.title field contains “medical”. A search for “dc.title:medical AND dc.description.abstract:technology” will return results where dc.title contains “medical” and dc.description.abstract contains “technology”.
