Regular Expressions for Consecutive Words

Question

I'm running a Apache pig script and I'd like to be able to look for a full string of words in a field. For example I would like to look for "following updates are downloaded and ready for installation"

The issue I'm having is that matches with RegEx only seems to allow me to enter single words to search for. So I end up looking for "following" & "updates" & "downloaded" & "ready" & "installation" and it doesn't matter how far apart they are. I've resorted to just including more words to try to lock down what I'm looking for but I wanted to see if looking for an entire string of consecutive words is possible.

Here is an example of my current filter.

downloadFilter = FILTER windowsLog BY ($16 matches '^(?=.*?(following))(?=.*?(updates))(?=.*?(downloaded))(?=.*?(ready))(?=.*?(installation)).*$');

Example record I'm trying to hit.

Why not simply search for the following regex:

'.*Download Completed.*'
