Search behavior

In the search, the following parameters can be used:

  • "": Phrase search. The words you entered must occur exactly as entered in the search results. Example: "Metrological Services"
  • -: NOT operation. A word can not appear in the search results. Example: "Metrological Services" -"Verification Act"
  • *: Substring search. Example: "Metrological Services" measure* finds "Metrological Services" measures and "Metrological Services" measurement

If you enter more than one search term, the individual words are connected with an "AND".
