Match From a Group of Words

def has_word?
  text =~ /((Word1)|(Word2))/
end

This is what I do now and it works but I feel like there is a better ruby solution. What's the right way to do this?

You may have some special situations to solve that aren't covered by your current approach. Here are some common solutions for these types of

Match regardless of case

/Word1|Word2/i

Avoid finding a match in the middle of a word

/\b(Word1|Word2)\b/

Match only the exact string

/^(Word1|Word2)$/

Matching variable lists of strings

def get_match(strings)
  Regexp.new(strings.join("|"))
end

get_match(["Words", "word", "terrible", "one-way", "don't"])
get_match(["week", "month", "year"])

Match longest word before shorter

def get_match(strings)
  Regexp.new(strings.sort.reverse.join("|"))
end

get_match(["Yes", "Day", "Yesterday", "Daytime"])
