Simple Search

To search all of Open Science, use the search box at the front page:

  • The word(s) you enter in the search box will be searched against the bibliographic fields of each item's record. The search engine ignores stop words, e.g. articles ("a"), conjunctions "and") or frequently used prepositions ("in").
  • Truncation: Use an asterisk (*) after a word stem to get all hits having words starting with that root, for example: thea* will retrieve Theater, theatre, Thealtralität etc.
  • Stemming: The search engine automatically expands words with common endings to include plurals, past tenses ...etc. (Europa will retrieve "Europas" or "Europapolitik".)
  • Phrase Searching: To search using multiple words as a phrase, put quotation marks (") around the phrase, e.g. "renewable resources".
  • Exact word match: Put a plus (+) sign before a word if it MUST appear in the search result. For instance, in the search "erneuerbare +Energien" the word "erneuerbare" is optional, but the word "Energien" must be in the result.
  • Eliminate items with unwanted words: Put a minus (-) sign before a word if it should NOT appear in the search results. For instance, in the search "erneuerbare -Energien" you will get items containing the word "erneuerbare", except those that also contain the word "Energien".

Advanced Search

In the advanced search you have the possibility to add further facets and operators to the simple search slot to refine your search:

  • Facets: You can choose from the following facets using a drop-down menu: Author, Title, Date issued, Subject, Publication type, Organisational unit, Description, Advisor, Identifier, Has File(s). You can combine any number of facets to refine your search even further. Please do not forget to always click on the "Add" button on the right hand side, otherwise your search will not be executed correctly.
  • Operators: In addition to the facet, you can select four different operators from a drop-down menu to determine the relationship between the selected facet and the search term: Contains, Equals, Not Contains, Not Equals. Please do not forget to always click on the "Add" button on the right hand side, otherwise your search will not be executed correctly.

Narrow/Sort search results

You can further narrow down your search results using the facets available in the right sidebar, which you can simply click on. Available are: Author, Subject, Publication type, Date issued, Organisational unit.

You can sort your hit list according to your wishes. To do this, you can make settings in various dropdown menus:

  • Results/Page: here you can determine how many hits per page should be displayed.
  • In order: here you can specify whether the list should be displayed in descending or ascending order.
  • Sort items by: here you can specify whether the hit list should be sorted by Relevance, Title or Issue date. Relevance means that the metadata field in which the search term occurs is decisive for sorting.
  • Authors/record: Here you can determine how many hits should be displayed. The default setting is that all hits are displayed.

Please do not forget to click on the "Sort again" button, otherwise your sorting will not be executed.
