+summary: Package search on pkg.go.dev has been updated, and you can now search for symbols!
+---
+
+We are excited to launch a new search experience on [pkg.go.dev](https://pkg.go.dev/).
+
+These changes were motivated by
+[feedback we've received](https://golang.org/issue/47321) about the search
+page, and we hope you enjoy them. This blog post provides an overview of
+what you can expect to see on the site.
+
+## Grouping related package search results
+
+Search results for packages in the same module are now grouped together. The
+most relevant package for the search request is highlighted. This change was
+made to reduce noise when several packages in the same module may be relevant
+to a search. For example, searching for "markdown" shows a row listing "Other
+packages in module" for several of the results.

+
+Results for different major versions of the same module are also now grouped
+together. The highest major version containing a tagged release is highlighted.
+For example, searching for "github" shows the v39 module, with older versions
+listed as "Other major versions".

+
+Lastly, we have reorganized information related to imports, versions, and
+licenses. We also added links to these tabs directly from the search results
+page.
+
+## Introducing symbol search
+
+Over the past year, we have introduced more information about symbols on
+pkg.go.dev and worked on improving the way that information is presented. We
+launched the ability to view the API history of any package. We also label
+symbols that are deprecated in the documentation index and hide them by
+default in the package documentation.
+
+With this search update, pkg.go.dev now also supports searching for symbols in
+Go packages. When a user types a symbol into the search bar, they will be
+brought to a new search tab for symbol search results. There are a few
+different ways in which pkg.go.dev identifies that users are searching for a
+symbol. We've added examples to the pkg.go.dev homepage, and detailed
+instructions to the [search help page](https://pkg.go.dev/search-help).
