Result Sets 

What is it? 
During any session, you always have a number of result sets. Select one, press [Enter] and see the brief display for browsing. The current result set is always available on the long button on the lower right side and can be activated from there. 

What can I do with result sets? 
If you activate one, you can sort it, and you can afterwards go to the View and Export menues and have it displayed in short or full, or export it. 
Sorting of result sets is also possible, butonly for sets smaller than 16.000 items: In the result window, position the triangle to the desired sort point (using the buttons [<<<] and [>>>]), then click [SORT], or use [Up/Down] to change the sort direction. (Tip: Click [>>>] or [<<<] only once, then press Enter and hold it down to move the triangle more quickly - which is not possible with the mouse alone.)

Boolean Combinations 
Situation: The current result set A is visible on the long button. Now select another result set B from the list, but do not press [Enter]. 
Combine it with the current set using these key commands or buttons: 

   +  [AND] : Intersection of A and B (logical AND) 
       The new set will contain just the records A and B have in common. 

   /  [OR] : Union of A and B (logical OR) 
      The new set consists of A and B combined, containing all records occurring in either A or B. 

   -  [NOT] : Difference of A and B (logical NOT) 
      Members of B are removed from A, if they occur there, too. Thus making A smaller. 

The new result sets can be combined with yet others in the same way. 

The same key commands can be used in the index window as well. There, they act directly on the lines of the index, always combining the record sets behind the lines with the current set.
