Sby Slack
Search messages
Searches messages and files in public channels, narrowed by channel, person and date.
Description
Use it to see what the team has already said about an account before reaching out; narrow a query with `in:`, `from:`, `before:` and `after:`. `slack_search_public_and_private` also covers private channels and DMs, with the user's consent. The Web API's `search.messages` needs a user token, so it is not listed here beside the bot-token API.
