The best way to find what you are looking for is to use the search function.
There is no need to end your search words in an asterisk (*) to ensure sufficient coverage. You can simply enter the first few letters of the desired search word. For example, the search word “radia” will show you all words beginning with that string of letters, including “radiation”. The same rule applies to all search forms found on the service.
Delimit the search words with spaces. A space is equal to the AND operator.
The quick search field can always be found at the top of each page. Searches entered in this field cover all texts and documents available in the service.
The quick search function is predictive, which means that results matching the search word you enter are provided in a dropdown below the field. The results change dynamically as you edit the search word. If you cannot find what you are looking for among the suggestions, click the Search button to view the full list of results.
Document type-specific search functions can be found on the left side of the page.
To access the advanced search, click the link at the top or bottom of the page. Links to document-specific search functions can be found on the left side of each document.
On the advanced search form, you can conduct searches with all words in the field, any words in the field, an exact phrase or without search words. The exact phrase field does not require quotes around the phrase.
The proximity search enables you to focus the search on documents in which the search words are at a specified distance from each other. The maximum distance for search words is one hundred words.
Limiting the search on the results page
Limit your search based on document type using the selections on the left side of the results page.
The search results can also be sorted according to time of publication or relevance. Relevance means the importance of matches in the search in question. By default, the results are sorted by time in a descending order, i.e. the latest search results are shown first.
You can also select the number of hits shown on one page.
