Extended Query

Categorical states

In this query control the categorical states are listed. If pictures or colours are assigned to the categorical states, they can be viewed by clicking on the state name (see picture below). You may switch off automatic loading of the resource view by clicking the button (“no web”), which will be indicated by a yellow symbol background. If this “no web” option is activated, only local resources, e.g. colours, will be shown. If during loading of remote resources an error occurs, e.g. due to a timeout, the “no web” option will automatically be activated. 

You may change the display order of the states between the standard numeric order , alphabetical order and reverse alphabetical order by clicking the appropriate button. If the state list exceeds the standard height of the control, a scroll bar will show at the right side of the state list. You can enlarge the control by clicking the button at the lower left side (see picture above). To return to the standard size, click on button  (see picture below).

Categorical states that are not checked are not relevant for the filter. If you want to search for a categorical state that is NOT present, check the option invert behind the categorical state name (see picture below). You may search for descriptions that do not have selected any of the categorical states by checking option no value.

By default all categorical states of a descriptor that are selected must be present in the matching descriptions. You may change this logical AND to a logical OR by clicking on the symbol & behind the no value check box, which will change to symbol (see picture below). Now all descriptions will match, which include one of the selected states.
