Answer 1

If you are trying to match words use \b as the word delimiter, like this:

\b[A-Za-z]-\d+\b

from this reference:

\b - Matches at the position between a word character (anything matched by \w) and a non-word character (anything matched by [^\w] or \W) as well as at the start and/or end of the string if the first and/or last characters in the string are word characters.
