This filter is used to display all pieces of equipment associated with the selected tag. For example, with this filter you can obtain all the equipment tagged as "regulatory".

Please note that if you select more than one tag, you will see the option "AND" or "OR" next to it.
If you leave the default choice "AND", you will find the equipment that have all the selected tags (e.g. as in the screenshot below, you will see all the equipment that have the tags "machine critique" and "Regulatory" simultaneously).

If you select the "OR" option, you will find all the results matching at least one of the selected tags (e.g. you will find the equipment that have the "machine critique" tag, but that have not the "Regulatory" tag, and vice versa).
