• Please note: All your entries filled in or chosen in the separated fields (simple or advanced search) are connected by AND, i.e. every additional entry decreases the number of results.

• With regard to an useful search the maximal number of hits is limited to 100. If your search does not provide a desired result, you have to reformulate your search terms by using more or different keywords. Please use also the categories of our "advanced search".

• Please note: If you are using the "free text"-search, your entries must contain at least three (3) characters.
  

• Please note further: The search functions only provide "exact search", which report items ONLY if they exactly match your input. Certainly you can add "*" to a part of word in order to extent your search.
  
  Example:
  
  The entry "mosque" will only report items which exactly match this entry. If you want to extent your search, it would be useful to write "mosque*" or just "mosq*".
