How can I split a string in zshell and capture a substring-to-end-of-line?

I have a string I would like to split into a substring and return the second subset of the result as a string. How can I do this in zshell?

I can split at a keyword and return the next word of the substring like this: 

line="quick brown fox jumps over sleepy dog"
splits=${(MS)line##over*}
nextword=$splits[(w)1] #<-- returns "sleepy"

How can I get the entire substring after the split such as "sleepy dog" or "sleepy brown dog" (if the string contains more words)? In essence, what I'm looking for in zshell is the awk equivalent of:

echo "quick brown fox jumps over sleepy dog" | awk -F'over' '{print $2};'

A slightly different approach:

[[ $line =~ "over (.*)" ]]
next_word=$match[1]  # or just $match

You can use a negative range offset (-1 in this case) at the end of your splits indexing. To get from sleepy all the way up to the last element, you could just use $splits[(w)1,-1].
