How to subset a file with searchString argument.

From a question I was asked in an email

I would like know how can I change this searchString to download others variables and where can I call this new searchString in my code.

The searchString argument can be used in a few of the Herbie methods. For example:

H = Herbie('2021-01-01')
searchString = 'TMP:2 m'  # search for 2-m temperature

H.read_idx(searchString) # read index lines that match the searchString (this is a great way to test your searchString)
H.download(searchString) # download a subset of the file that matches the searchString
H.xarray(searchString) # read the data into xarray that matches the searchString

More examples of how to set searchString is in the docs. Essentially it can be any regular expression to look through the index files.
