Combined searching is possible using the Boolean Operators OR, AND, NOT. It is important that all Boolean operators are caps. This advanced search gives you the option to choose the operator (OR - AND - NOT).
  • OR: The OR operator is the default conjunction operator. This means that if there is no Boolean operator between two terms, the OR operator is used. The OR operator links two terms and finds a matching document if either of the terms or both exist in a document.
  • AND: The AND operator matches documents where both terms exist anywhere in the text of a single document.
  • NOT: The NOT operator excludes documents that contain the term after NOT.

Fuzzy Search


Fuzzy searches: in cases you are not sure about the right spelling, it is possible to do a fuzzy search using the tilde(~): searching 'roam~' will have as result foam as well as roams.

Regular Search


Compose your own search-string. E.G. 'chemistry AND techniques NOT tests AND language:eng'. This search-string will have as result dissertations in English that have to contain the words Chemistry and Techniques and that may not contain the word tests.
