Upgrade StorageModes for selecting multiple tags (OR vs. AND)
Currently, as far as I gather, multiple tags can only be selected in the AND mode when used for filtering (meaning that the filtering results include only entries that have ALL the selected tags).
I think it is also very useful to be able to select multiple tags in an OR mode (meaning that results shall include entries that have ANY of the selected tags). This will make it easier to filter entries based on related tags (which are often the result of automated tagging).
There appears to be a similar ticket from 4 years ago, although without description I can only guess what is meant by the rather generic title (#533, https://www.zotero.org/trac/ticket/533).
