### Criteria, operators and groups

The advanced search allows you to look for articles by combining several criteria with AND and OR operators.

To add a criteria, click on the (+) icon:

When several criteria are present, they must be combined with a boolean operator:

Criteria can be grouped to refine your search. Groups are created using parentheses:

### Advanced search: a case study  


For example, let us search for papers:

- submitted by one specific author
- for two different special issues

The search request will look like this, where we specify:

- the author's login in the first line
- then search the topical issues by using a group:
