# Suchi articles

> Every article is a filed document, and like any document in Suchi, it wears its label.

## Articles

- [Why Suchi files every document under a number](/blog/numbered-filing/index.md): Why Suchi gives each document one short numbered home, keeps the tree at one category level, and recovers the other relationships through search and tags.
- [Linking scans to their physical originals](/blog/archive-serial-numbers/index.md): A retained QR label gives a physical document and its scan one durable number. The same label can also split a feeder stack into documents without sacrificing the first page.
- [Keep a document's history and its related documents](/blog/versions-and-links/index.md): Replacement versions keep a document's earlier copies underneath the current one, and document links connect it to related documents. Both are deliberate: Suchi doesn't guess either relationship.
- [Keep the folder layout you already use](/blog/keep-your-folder-layout/index.md): Suchi can rebuild the flat or nested folder layout you already use from each document's own facts. If you change the layout later, the files move with it.
- [Find every invoice over €1,000](/blog/find-invoices-by-amount/index.md): Full-text search can find one invoice by its words. Typed fields let Suchi answer questions across the archive: amounts, dates, status, and other values that need type-aware comparisons.
- [Using Suchi Companion away from home](/blog/suchi-companion-away-from-home/index.md): Suchi Companion captures documents for a self-hosted archive, searches the reachable server, and keeps selected documents on phone for offline use.
- [Sharing a document with an expiring link](/blog/share-documents-with-expiring-links/index.md): Suchi shares can expire, use a password, and be revoked while the file stays on your server, with clear limits once someone downloads a copy.
- [Keeping a Suchi archive recoverable for thirty years](/blog/thirty-year-archive/index.md): Suchi uses one server process and separates two recovery jobs: whole-instance backups restore the archive exactly, while takeouts provide ordinary files for migration.
- [From inbox to filed: how Suchi handles a new document](/blog/filing-loop/index.md): How a new scan moves through Suchi’s filing tree, exact rules, local matching, optional classification, and review before it reaches its category.
