 ### How type-based search works
 
-In a complex type-based search, Rustdoc always treats every item as literal.
+In a complex type-based search, Rustdoc always treats every item's name as literal.
 If a name is used and nothing in the docs matches the individual item, such as
 a typo-ed [`uize -> vec`][] search, the item `uize` is treated as a generic
 type parameter (resulting in `vec::from` and other generic vec constructors).

   * Searching for lifetimes is not supported.
