All words you enter are searched for in all categories (author, title, year of publication, subject heading, etc.) as well as all types of media.
If you do not use any logical operators such as ODER/OR or NICHT/NOT, the system will automatically search for all the entered terms (UND/AND). Please note that if you search without logical operators, you will only receive results which contain all of the search terms exactly as you entered them.
Next to the search field, you can choose which collection you want to search.
The advanced search allows you to search for a combination of different categories such as title, author, ISBN, subject classification. You can also filter your search by material type, language, date of publication, and collection.
If you want to enter several search terms, you can use logical operators (UND/AND, OR/ODER, NOT/NICHT) to tailor your search. These must be capitalized.
If you would like adjacent words to be applied as phrases, put them in quotation marks. The advanced search also allows you to choose the setting “contains the exact phrase.” This allows you to combine single words or phrases with each other in your search.

climate change impact | Search for resources containing both the phrase "climate change" and the word "impact" |
climate change OR "global warming" | Search for resources containing either the words "climate change" or "global warming" or both phrases |
To group terms within an inquiry, you must put them in parentheses. It may also be advantageous to include logical operators.

The subject heading is in German regardless of the publication’s language.
All available subject headings can be found in the OGND (Gemeinsame Normdatei).
