# Searching topics

You can search for topics associated with repositories on GitHub.

## Search GitHub for topics

You can search for topics on GitHub, explore related topics, and see how many repositories are associated with a certain topic.

1. Navigate to search page (`https://[hostname]/search`).
2. Type a topic keyword.
3. In the left sidebar, to narrow your search to topics, click **Topics**.

## Narrowing your search with search qualifiers

If you want to explore repositories about a certain topic, find projects to contribute to, or learn which topics are most popular on GitHub, you can search topics with the search qualifiers `is:featured`, `is:curated`, `repositories:n` and `created:YYYY-MM-DD`.

The `is:featured` search qualifier will narrow search results to the topics with the most repositories on GitHub. These topics are also featured at <https://github.com/topics/>.

The `is:curated` search qualifier will narrow search results to topics that community members have added extra information to. For more information, see the [explore repository](https://github.com/github/explore).

You can filter topics based when they were created using the date parameter and `created:` or based on how many repositories are associated with this topic using `repositories:n`. Both of these qualifiers can use the [greater than and less than range qualifiers](/en/enterprise-server@3.22/search-github/getting-started-with-searching-on-github/understanding-the-search-syntax).

Date formatting must follow the [ISO8601](http://en.wikipedia.org/wiki/ISO_8601) standard, which is `YYYY-MM-DD` (year-month-day). You can also add optional time information `THH:MM:SS+00:00` after the date, to search by the hour, minute, and second. That's `T`, followed by `HH:MM:SS` (hour-minutes-seconds), and a UTC offset (`+00:00`).

When you search for a date, you can use greater than, less than, and range qualifiers to further filter results. For more information, see [Understanding the search syntax](/en/enterprise-server@3.22/search-github/getting-started-with-searching-on-github/understanding-the-search-syntax).
