Search tips and tricks 🔎

Discourse’s search capability is feature-rich. It comes with many of filters and criteria. When you use these from the advanced search form, it automatically appends the relevant syntax to your query.

For instance, if you select In my messages, it will append in:personal to your search query.

This topic aims to list other filters that aren’t available in the advanced search form, filter aliases, results orders and other search-related tips and tricks.

It will not cover filters available from the advanced search form.

Search for Exact Words

Discourse’s search uses a technique called Stemming. It allows the search engine to find related words.

For example, a search for “improv” returns:

  • improve
  • improving
  • improvements
  • improved
  • improver

And so on.

While this is often beneficial, there might be occasions when you want to search for the exact word. This can be achieved by enclosing your word with spaces and double quotes, like so:

" improve "

This ensures that it will search only for the word “improve” and exclude other related words.

For instance:

:information_source: Note that because of the spaces considered as mandatory since they’re wrapped with double quotes, it will not return “improve” if it’s the first or the last word of a post since it won’t be preceded or followed by a space.

Example: Search for @mentions

Currently, searching for @mentions is not supported. However, using the above method, you can achieve it like so:

https://meta.discourse.org/search?q="%20%40canapin%20"

This query will look specifically for @canapin (enclosed in spaces).

Search Alternative: Topic List Filter

An experimental /filter feature is available that supports many filter types. You can learn more on the official topic:

All search filters and parameters can be found in search.rb. Look for the advanced_filter methods.
