How to use parametric search?

  • You can choose the number of results per page: 10, 25, 50, 100 or all results.
  • You can use the filters in the second row to narrow down the selection. Click on one or more values in the lists you want to select. Or use the sliders by dragging the handlers or fill in the fields.
  • The common characteristics are parameters with the same value for all type numbers.
  • You can find more information about a type number by hovering over the type number and click on one of the links in the pop-up.
  • You can compare two or more type numbers by selection the checkboxes for the type numbers and click on Compare. All other rows will be hidden.
  • To hide the row with filtering options, click on the grey bar with arrows below the options.
  • To add or remove columns with parameters click on the Add/Remove parameters button on the top right. You can check the columns you want to see.
  • You can change the order of the columns by dragging and dropping the columns to the desired position.
  • You can download the results of your (filtered) selection to Excel by clicking the Download Excel button.
