I use folder hierarchies for broad strokes categorisation. Tags for denoting state - whether a file is a piece of work that needs invoicing for, for example. And I use Houdah Spot for searching. I’m a writer who uses Markdown for everything, so I put MultiMarkdown metadata in files (client, invoice amount, etc) and that’s useful for searches and grouping (and for scripts to build invoices based on the tags and metadata)
