   9 You can add alias(es) to an item when using the `rustdoc` search through the
  10 `doc(alias)` attribute. Example:
  11
  12 ```rust,no_run
  13 #![feature(doc_alias)]
  14
  15 #[doc(alias = "x")]
  16 #[doc(alias = "big")]
  17 pub struct BigX;
  18 ```
  19
  20 Then, when looking for it through the `rustdoc` search, if you enter "x" or
  21 "big", search will show the `BigX` struct first.
