I know you can do in:#channel to only get results from a channel, but is there a way to filter out results from a channel? A lot of our channels are spammed with automated messages and it adds noise to the search results.
I found that this is possible as a global setting (which is well short of convenient, but still may be useful). According to this page §"Exclude channels from search":
- From your desktop, click your workspace name in the top left.
- Choose Preferences from the menu.
- Click Search. (I had to click "Advanced" under which there was a "Search Options" section)
- Under Don't search these channels ("Exclude these channels from search results" for me), click the box to pick channels to exclude.
