+### Add aliases for an item in documentation search
+
+This feature allows you to add alias(es) to an item when using the `rustdoc` search through the
+`doc(alias)` attribute. Example:
+
+```rust,no_run
+#![feature(doc_alias)]
+
+#[doc(alias = "x")]
+#[doc(alias = "big")]
+pub struct BigX;
+```

+"big", search will show the `BigX` struct first.
