 This function supports a range of named parameters that adjust its functionality:
 
+- `:animated` (boolean): Enable and disable background animation.
+- `:case-sensitive` (boolean): Whether the matching algorithm should respect differences in case. The default is `false`.
 - `:full` (boolean): If true, occupy the entire screen.
+- `:headers` ([]string): Provide a title for each column. This mostly used for filtering tabular data.
 - `:prompt` (string): The text that will be shown beneath the search window.
 - `:reverse` (boolean): Display from the top of the screen (rather than the bottom.)
-- `:animated` (boolean): Enable and disable background animation.
