Matchtext to find a series of words

[J. Landman Gay]

I need a matchtext/regex that will find a series of words in a block of
text, no matter whether they are together or not, and ignoring carriage
returns. For example:

See if all of these words: dog cat dinosaur

are in this text:

"The purple dinosaur inadvertently stepped on the cat.<cr>
The white dog howled."

Should return true. Is there such a thing?
