Channels, threads & search
How this is scored
The daily surface: channel model, threading, mentions, files, and whether search can find a decision made eighteen months ago.
0 — Flat group chats with no threads; search covers recent messages only, and history is capped.
3 — Channels and direct messages with basic search, but threading is awkward or absent and file handling is a plain attachment list.
5 — Public and private channels, real threads, mentions and reactions, file sharing with previews, and full-text search across the whole history.
8 — Cross-organisation or guest channels with clear boundaries, message editing history, pinned and saved items, search with filters by channel, person and date, and a documented history limit or none at all.
10 — The archive is a working knowledge base: search that ranks well across years, threads that stay readable, channel lifecycle management (archive, rename, merge) without losing history, and export of a conversation in a form a human can read.
The Team Lead
Chat rooms are private to their participants with a single room administrator, and we found no public information on threading, mentions or pinned items — the readable-channel model I need is not what the captured pages describe. Search is the bright spot, with operators for author, label, hashtag and date plus files, and archived groups keep their posts findable with an Archived label while the group can be restored with chat room and Drive documents intact; but deleting a room permanently deletes its messages for every participant. 1 2 6
