4.4.1.14. Logical operators

  • Comparison operators

    If you search with variables, you can use comparison operators, not only the actual-equal (=), but all common mathematical operators.

    • = : Is equal to

    • < : Smaller

    • > : Larger

    • <= : Smaller equals

    • >= : Greater than or equal to

    Example:

    Hexagonal blade L>200
    

  • Link operators

    You can also link terms and numerical values with "AND" or "OR" and exclude certain terms with "NOT".

    [Note]Note

    The search term is not case-sensitive.

    Operators such as AND, NOT, OR, on the other hand, must be capitalized.

    • NOT: Exclusion of a specific term

      Examples:

      • Round cylinders should be excluded.

        Cylinder NOT round
        or
        Cylinder ! round

        [Note]Note

        No space is allowed between the exclamation mark (!) and the term to be excluded.

      • If you want to exclude a sequence of terms, you must put them in brackets.

        Handwheel !( Form V )
        

    • AND: All terms must occur or all conditions must be fulfilled.

      [Note]Note

      The AND operator can also be omitted.

      Screw AND shank
      
      is synonymous with
      
      Screw Shaft

      Examples of the AND operator

      • 16.2 21 90

      • Hexagon Bolt L = 400
        

        or

        Hexagon Bolt AND L = 400
        

      • Hexagon head screws AND >200

        The system searches for hexagon bolts with any value greater than 200.

      • Hexagon Bolt L>=140 L<=160
        or
        Hex Bolt L>=140 AND L<=160
        

      • Hex Bolt L = 120 AND D = 22
        

      • IDNR>=23012001 AND IDNR<=23012025

    • OR: It is sufficient if a term occurs or a single condition is fulfilled.

      Example of the OR operator

      • Hexagon Bolt OR Cap Bolt

        The result therefore contains both hexagon head screws and cheese head screws.

      • ( Hexagon bolt ) OR ( Head cap bolt )
        

        is equivalent to

        Hexagon bolt OR Head cap bolt

        The brackets are dispensable. The space is equivalent to AND.
