Result lists are sorted according to relevance settings defined by University Library specialists (compare: Improving Result Lists).
Form most purposes, the publications listed on the first pages of result lists should be quite satisfying. To modify the order in which journal articles are ranked in the Articles+ scope, you can select the disciplines most relevant for you in your personal Primo settings.
To do so, click on "Personalize" on top of the result list in Articles+ scope.
Consider the following example to get an idea of how you can expect to improve the ranking for relevant articles, depending on your selection of disciplines:
Search term: drone ↔ Discipline: either Biology or Political Sciences
Primo will display articles from journals in the selected disciplines higher on the result list.
