SpamAssassin uses Perl regular expressions. There is lots of
information available on the Internet.

For your question, you can match on a list of words with an expression
like this:
/word1|word2|word3|word4/
However, keep in mind that without anchoring the expression, you can
match on substrings such as "blahword1blah". To avoid that, you can
match like this:
/\b(?:word1|word2|word3|word4)\b/
The "\b" matches a word boundary (beginning or ending of a word) and the
parenthesis group the alternates together so that the expression says
"word boundary, one of these words, then another word boundary". The
"?:" prevent the group from capturing the match and speeds it up a bit.
