+## Custom search engines
+
+If you find yourself often referencing online Rust docs you might enjoy using a custom search
+engine. This allows you to use the navigation bar directly to search a `rustdoc` website.
+Most browsers support this feature by letting you define a URL template containing `%s`
+which will be substituted for the search term. As an example, for the standard library you could use
+this template:
+
+```text
+https://doc.rust-lang.org/stable/std/?search=%s
+```
+
+Note that this will take you to a results page listing all matches. If you want to navigate to the first
+result right away (which is often the best match) use the following instead:
+
+```text
+https://doc.rust-lang.org/stable/std/?search=%s&go_to_first=true
+```
+
+This URL adds the `go_to_first=true` query parameter which can be appended to any `rustdoc` search URL
+to automatically go to the first result.
