søgning

You don’t need special codes or heaps of knowledge to use the search system, but it has a search language that enables you to make very precise searches – in each individual field of a library item. A complete summary is shown at the bottom of the page.

The summary below distinguishes between single word searches and exact searches.

You can use single word searches for making standard searches. Enter each individual word in a string, truncate the words, combine several words or make a string search (i.e. the words have to appear in a specific order).

An exact search means that you have to indicate the entire content to get a result. Use this if you would like to deselect results that contain your search expression as well as unwanted words. If, for instance, you want to search for Lyngby as a subject, but don’t want books about Hans Lyngby Jepsen, you can search for lsubj:lyngby. This gives you fewer results than su:lyngby, which returns results about both the town Lyngby and the author Hans Lyngby Jepsen.

The search author_normalised:"andersen h c" therefore gives a completely different result than author_normalised:"andersen h c 1805". Both search sets are contained in au:"andersen h c", but the string author_normalised:(andersen\ h\ c*) contains all variations of Hans Christian Andersen with different dates of birth.

NOTE that for all specific searches in individual fields, you must use the exact character set (except for small/capital letters).
