Word Stem Search / Stemming

 Each search is automatically executed as a word stem search. For example, a search for "climate" will also return results for "climate change."

 
What results are shown when searching with multiple terms?

• For two search terms, both must appear in the result.
• For three to five search terms, all but one must appear.
• For six or more search terms, 75% of all terms must appear.

 
Sorting of the Results List

The results are sorted by relevance. The ranking is determined by:

• In which metadata field the search term appears
• Whether the term is found in the full text
• For multiple terms: Results where the terms appear close together are ranked higher.

Syntax: fieldname:content
Example: dc.subject:climate

Phrase search:

To search for exact word groups, place them in quotation marks.
Example: "climate change in Switzerland"

Search for fields with any content:

To find all entries where a field contains any content:
Example: dc.subject:*

Search for empty fields:

To find entries where a field is empty:
Syntax: -fieldname:*
Example: -dc.date.issued:* shows all entries without a publication date

Combining fields:

Using parentheses and the Boolean operators AND or NOT, you can combine fields when searching – even in fields that are not filters.
Example: (dc.subject:climate AND dc.language:de)
