When adding a reference from the library search, you can filter based on "Type" and "Available here" facets in Leganto. This is great, but it would also be helpful if you could exclude facets as well, like you can in Primo. For instance, if you don't want Open Access records you should be able to exclude them. The "Type" facets are usually mutually exclusive (so isn't as relevant to exclude), but this is not true for the "Available here" facets. References can for instance be both "Open access" and "Peer reviewed" at the same time.

Our specific use case is that Open Access records are sometimes lacking certain metadata and/or take focus away from records that are from purchased electronic collections that we want to use. We have cases where records from Institutional Repositories are chosen instead of the publishers hosted version, which can be detrimental in some cases. Therefore, it would be beneficial to be able to exclude these records in order to better see which record should be chosen.
