Subset
A subset of publications may be obtained by executing a selection expression in the Subset page.
The selection expression works by using functions which select a subset of all publications currently in the system. Operators can be used to combine these subsets. Paranthesis are used to determine the order of evaluation if the operators. A selection expression may be arbitrarily complex.
The list of selected publications can be viewed or downloaded in different file formats.

|---|---|---|
| - | minus | Difference between first and second set. |
| # | hash | Intersection between the two sets. |
| ^ | hat | Symmetric difference between the two sets. |
