Search - basic and advanced

In, you can choose between two ways to search - basic and advanced, depending on your task at hand.

Basic search

In many cases, the basic search will be sufficient.

Write in the search box what you are looking for. It can be a title, an author, a topic, or a mix. If you remember part of a title, the author’s first name, and that it was a book - just write that, for example:

  • "to kill harper book"
  • "murakami women"
  • "beatles abbey"
  • "quiet girl dvd"


Search result


If you know which material type you are looking for, you can choose material type up front to only search for i.e. films

In the search results, you will have several options to continue working with your search.

Use the filters to refine by material type, physical/digital material, language, fiction or non-fiction, and more.

The order of hits in the search result depends on several factors in the underlying ranking. It is continuously adjusted, but the following rank highly:

  • popularity
  • new materials
  • Danish materials
  • exact hits

Advanced search

As a student or researcher, you may need to do more advanced searches. Go to the advanced search page. Click Advanced next to the search field.

Field search

You can now search using field search, where you compose the search using fields connected by the operators AND, OR, NOT.

Advanced search fields

Be aware that if you choose to edit your search in CQL the changes will not appear in the boxes in field search. Once you start editing in the CQL-field you will not be able to switch back to field search. 


Further Limitations

You can narrow down your search to a specific time interval, a particular language or material type and age group using the dropdown boxes at the bottom of the advanced search page.

Command Search

Go to "Edit in CQL" in order to search using search operators. The search operators are specially developed for the search method used for advanced search.
