What tags are
Tags are short labels you attach to documents. Unlike a collection, which a document belongs to one at a time, a document can carry as many tags as you like. That makes tags good for cutting across your library — for example, marking everything that's about a particular client, or everything you still mean to read.
Adding tags
Add tags from a document's edit form — see Documents. Type a tag to attach it; a tag you haven't used before is created the first time you add it, so your set of tags grows as you go.
Filtering by tag
In Documents, filter your library by tag to narrow the list to just the documents that carry it. You can filter by more than one tag at a time to focus on documents that share several labels.
Tags vs. collections
- Use a tag when a label applies to documents scattered across different collections.
- Use a collection when you want a single home for a project or topic's documents.
The two work together: a document can sit in one collection and still carry several tags.
