Unifying, Forming the Intersection of, or Reducing Sets of Hits

Prerequisites

You have display authorization for the set of hits groups in which the sets of hits you want to unify, form the intersection of, or reduce are located.

Procedure

Load one of the sets of hits that you want to unify, form the intersection of, or reduce (see Loading Sets of Hits).

Choose one of the following steps:

Choose if you want to unify sets of hits.
Choose if you want to form the intersection of sets of hits.
Choose if you want to reduce sets of hits.

The screen from which you loaded the first set of hits appears.

Choose Utilities ® Set of hits ® Load.

The group overview of the sets of hits is displayed.

Double-click on the set of hits that you want to unify with the first set of hits, with which you want to form an intersection with the first set of hits, or whose specifications you want to reduce the first set of hits by.

Note

Search criteria entered on the initial screens are not taken into account when the sets of hits are loaded, unified, reduced, or when intersections are formed.

Result

Unifying Sets of Hits

A set of hits that contains all the specifications from the original sets of hits is formed. Specifications that appear in both sets of hits are only included once (union).

Forming the Intersection of Sets of Hits

A set of hits that contains only specifications that appear in both original sets of hits is formed (intersection).

Reducing Sets of Hits

A set of hits that contains only specifications that appear in the first and not in the second set of hits is formed.

Example

Set of hits 1 contains the specifications EHS_01, EHS_02, and EHS_03. Set of hits 2 contains the specification EHS_03.

If you form the intersection of the set of hits, a set of hits is formed that contains only the specification EHS_03 since this is the only specification that occurs in both the original sets of hits.
If you reduce the set of hits 1 by the set of hits 2, a set of hits is formed that contains the specifications EHS_01 and EHS_02.
