Help on Search

Simple search criteria

Search is not case-sensitive.

Search terms must comprise at least 3 characters.

When entering multiple keywords, use blanks as separators. All keywords are automatically linked with a logical "AND".

The results are ordered by the frequency of the occurrences of the search term.

The subsequently described search options can be combined. Fuzzy Search and Dublic Core Search can only be used with the Keyword Search, while truncation, Boolean Operators, phrase search and distance search can also be used with the Extended Search.


Search terms can be truncated using the characters "*" and "?". The asterisk serves as a placeholder for any number of characters, while the question mark replaces one specific character. Neither truncation operator may be used at the beginning of a word, but combining both operators is possible.

Boolean Operators

The search interface can handle the logical operators AND, OR and NOT to refine the query.

Phrase search

A phrase search is performed when multiple keywords are placed in quotation marks. The entered search terms appears in the exact specified phrase in the results.

Fuzzy Search

For this somewhat indistinct search method, one uses the tilde sign "~" at the end of a search term. The degree of similarity (between 0 and 1) can be parameterized. If no value is provided, the default setting used is 0.5.

Distance search

The distance search allows you to search for two terms, which occur within a certain distance from each other. To use this search, enter a phrase search (see above) and add the tilde symbol "~" followed by the maximum number of words within which the search terms must occur.

Dublin Core Search

You can specify to which Dublin Core metadata field you want to limit your search.
