"""
Search for all paths containing the specified string fragment in the
current directory (and its subdirectories, according to the specified
search depth). It traverses the directory tree, checking whether each
path (which can be the path of a file or subdirectory) contains the
specified slicing string `slicing`. If a matching path is found, it
produces these paths as results.
@param slicing
The path slicing, which can be any part of the path.
@param level
Recursion depth of the directory, default is deepest. An int must be
passed in, any integer less than 1 is considered to be 1, warning
passing decimals can cause depth confusion.
@param omit_dir
Omit all subdirectories when yielding paths. The default is False.
@param pure_path
By default, if the subpath is a directory then yield a `Directory`
object, if the subpath is a file then yield a `File` object. If set
this parameter to True, directly yield the path link string (or
bytes). This parameter is not recommended for use.
@param shortpath
Yield short path link string, delete the `dirpath` from the left end
of the path, used with the parameter `pure_path`. The default is
False.
