How to use the search engine:

Enter one or more search terms, separated by spaces. These can be words or parts of words. The search will return similar as well as exact matches.
You can refine your search in the following ways:

• Checking "English" limits the search to pages in German.
• Checking "Associated Terms" causes the search to include pages which are conceptually related to your search terms.
• "search phrase": Putting raised commas around your search terms causes the engine to search for that precise phrase. Otherwise, your search will retrieve all pages which contain at least one of your search terms.
• '+search -phrase': Adding '+' before a search term tells the engine to search only for pages where that term appears in the text. Adding '-' tells the engine to search only for pages where that term does not appear. Use these symbols without raised comma.
  
• '>search' : '>' before a search term makes it more important, otherwise '<' makes it less important. Use these symbols without raised comma.
