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.

The search feature allows you to exclude words from the result by putting a minus sign in front of a word.

Examples:

hot -potato

will only return messages containing hot, but not potato.

To exclude a channel from the results use searchTerm -in:channelName. Do not add a # in front of the channel name.

    Yes I know that but apparently that rule doesn't apply to channels. E.g. foo -in:#channel does not work Dec 20 '18 at 0:39

    works on my machine :-) yet I needed to include the # sign. May have changed recently.

    Interestingly, for me it only works if I don't include the #... 🤷‍♂️

  • For me both of below filters worked, just make sure you are using correct channel name my_search_term -in:#sfdc-pusher-alerts -in:us_demo_notes

I found that this is possible as a global setting (which is less than convenient, but may still be useful). According to this Help Center page (Under the "Exclude channels from search" section):

  1. From your desktop, click your workspace name in the top left.
  2. Choose Preferences from the menu.
  3. Click Search. (I had to click "Advanced" under which there was a "Search Options" section)
  4. Under Don't search these channels ("Exclude these channels from search results" for me), click the box to pick channels to exclude.

  • Looks like the article has changed since, and I can't find where the information has moved. Unfortunately, I didn't have the foresight to archive it either...

  • It seems to work only for public channels through Feb 3 at 16:28
  • This still works. Now under Preferences > Advanced > Exclude these channels from search results: Updated documentation link: slack.com/intl/en-ca/help/articles/… Jul 22 at 2:55
