Use the search box to find messages and replies that match the search terms that you enter. All channels that you are a member of in the current team are searched.
- Multiple-word search terms return results that contain all of the terms.
- When results appear, click Jump to view that post in the channel archive.
- File attachments and their filenames are not searched. If file attachments show up in the search results, it’s because they are attached to messages that match the search query.
- Archived channels can be searched as long as you are a member of that channel. To remove archived channels from your search results, you can leave those channels. If you are unable to see messages in archived channels in your search results, ask your System Administrator if Allow users to view archived channels has been disabled under System Console > Users and Teams.
- You can use search modifiers such as
from:daveto return results only from certain people or in certain channels. For more information about this, see the Search Modifiers section.
Like many search engines, common words such as
are (known as “stop words”), as well as two-letter and one-letter search terms, are not shown in search because they typically return too many results. See database documentation on MySQL and Postgres for a full list.
From: and In:¶
from: to find posts from specific users and
in: to find posts in specific public or private channels, as well as direct and group messages.
- For example: Searching
Mattermost in:town-squareonly returns messages in Town Square that contain

Mattermostin your direct message history with John Doe.
Before:, After: and On:¶
before: to find posts before a specified date and
after: to find posts after a specified date. Use both
after: together to search in a specified date range. Use
on: to find posts from a specific date. You can use the date picker to select a date or you can type it in YYYY-MM-DD format. For example:
website before: 2018-09-01will return messages containing the keyword

website after: 2018-08-01will return messages containing the keyword

Differences between MySQL and Postgres Search¶
By default, Mattermost uses full text search support included in MySQL and PostgreSQL. These databases have slightly different search behavior. Check Main Menu > About Mattermost to see which database you’re using.
- Email addresses do not return results.
- Hashtags or recent mentions of usernames containing a dash do not return search results.
- Terms containing a dash return incorrect results as dashes are ignored in the search engine.
- Hashtags or recent mentions of usernames containing a dot do not return search results.
