Wild cards
Wild cards (*, %, and ?) can only be used from the third character of a search term.

Place holders (truncation)
The truncation symbol (*) can stand for one or more characters (letters or numbers) in your search term. For example, enter "machine*" to retrieve entries containing the words "machine", "machines", "machinery", etc.
The search function can search for a maximum of three different search terms, such as civil*, engineer*, structur*.

You can link several terms in your search using “operators” as follows:

  • the “and” function: "AND" or a space:
     use "and" or a space if BOTH terms must be included in an entry
  • the “or” function: "OR" or the pipe symbol "|":
    use "or" or "|" if only ONE of the terms should be included in an entry
