Enter your search terms in the search input field. You can use the following operators to refine your search. Use the search-button to perform the search.

You do not need to pay attention to upper and lower case. The program also finds the entered terms as part of a larger character string.

Character search You can search for specific characters and character strings. This can be very useful when searching for paragraphs, for example. The following search parameters for specific searches are not available in this case. For character search, click on the arrow symbol on the right in the search input field and then on "Character search".

" " enclose word groups and restrict the search to these word groups as a whole or as components.

Example: "central care" finds central care and e.g. central care facility.

? is a placeholder for individual characters.

Example: Schmi?t finds Schmidt and Schmitt.

* is a placeholder for character strings.

Example: Schmidt* finds e.g. Schmidtbauer.

OR allows you to logically combine words and find pages that contain either one or the other search term.

Example: medicine OR hospital finds pages on which either medicine or hospital occurs.

AND allows the logical combination of words and finds pages on which both the one and the other search term occur.

Example: medicine AND hospital finds pages on which both search terms occur.

NOT excludes words or chains of words after the NOT.

Example: medicine NOT hospital returns all pages that contain medicine but on which hospital should not occur.

+ If you put a + in front of a term, this means that this term must appear on the page, but the other search term can appear optionally.

Example: medicine + hospital finds all pages where hospital appears or the combination of hospital and medicine.

~ A tilde, which is placed after a word, means, that words are searched that are similar to the entered word.

Example: laugh~ finds words like rough, though.

^ can be used in combination with a trailing number to give one term a higher weighting than the other by the factor of the number. This affects the order of the results.

Example: In hospital ^2 medicine the expression hospital is weighted twice as high as the following term.

(…) By setting brackets you can group queries clearly.

Example: (hospital OR medicine) AND clinic finds the pages that must contain clinic and on which either the words hospital or medicine can appear.
