Searching for Exact Words
Discourse uses a technique called Stemming to find related words. While this is often helpful, there may be times when you want to search for an exact word. You can do this by enclosing your word with spaces and double quotes, like so: " term ".
This ensures that it will search only for the word “term” and exclude other related words.
Example: Searching for @mentions
Currently, searching for @mentions is not directly supported. However, you can achieve this using the exact word search method:
https://meta.discourse.org/search?q=“%20%40username%20”
%20is how spaces are encoded in URLs and%40is how the@symbol is encoded.
This query will look specifically for @username (enclosed in spaces).
Combining Search Options
You can combine multiple search options to create more specific queries. For example:
-
status:open category:support tag:urgent after:2023-01-01 order:latest
This will search for open support topics tagged as urgent, created after January 1, 2023, and sort the results by the latest post. -
@jane_doe in:watching min_posts:5 with:images
This will search for posts by Jane Doe in topics you’re watching, with at least 5 posts, and containing images.
Permissions and Limitations
Some advanced search options may require certain user permissions or may be limited to specific user roles. For example:
-
in:all-pmsis only available to administrators, not to regular users or moderators. -
personal_messages:usernameis only available to administrators. -
in:whisperrequires whisper access. -
include:unlistedis only available to Trust Level 4 users and staff.
Always consider your user role and permissions when using advanced search options.
Search Alternative: Topic List Filter
A /filter feature is available that supports many filter types. You can learn more on the official topic: Topics list filter feature
Source Files
For a more technical look at these options, all search filters and parameters can be found in search.rb - look for the advanced_filter methods.
Additional Tips
-
You can also search for mentions of tags like #bug: https://meta.discourse.org/search?q=“%20%23bug”
-
Some filters may be added by plugins. For example, the Solved plugin adds:
-
status:solved: Returns posts from solved topics -
status:unsolved: Returns posts from unsolved topics in categories allowing solved marking
-
-
The Topic Voting plugin adds:
-
order:votes: Sort results by number of votes on the topic containing the post -
min_vote_count:X: Returns posts from topics with at least X votes
-
-
The Assign plugin adds:
-
in:assigned: Returns posts from topics assigned to someone -
in:unassigned: Returns posts from topics not assigned to anyone -
assigned:username: Returns posts from topics assigned tousername
-
-
The Poll plugin adds:

in:polls: Returns posts containing polls

Take some time to experiment with different combinations of filters and options to find the most effective search strategy for your needs.
