Search Options: what advanced search options does OPEN FAU support?

OPEN FAU offers the search (magnifying glass icon or https://open.fau.de/search) to perform complex searches.

By default, a Boolean “AND” search is performed when multiple terms are entered (see Wikipedia entry on https://en.wikipedia.org/wiki/Boolean_algebra#Boolean_operations). This will return results that include each of the terms. “OR and NOT searches are also possible. For example, a search for medical NOT care will return results containing medical but not care.

Phrase searches, such as “medical care” (in quotation marks), will return results that contain exactly the term “medical care”.

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”.
