Use Add as Filter to Define Search Parameters

To apply a filter, right-click on a property in the Entity Editor and select Add as Filter.
Figure 1.

The filter is added to the search field in the browser. If you add more than one filter type, it will be added to the search field, with the word AND.

If you want to change search criteria (part color for example), you can backspace to remove the number from the search field and a context sensitive menu is displayed containing the color palette.

Selecting a new part color automatically adds the number equivalent to the search field.
