cts:highlight() will do the highlighting around your search phrase, but
in order to create a partial context around the first match in the
paragraph it's necessary to write a fairly complex ad hoc function,
probably relying on fn:tokenize() to establish the context and then
fn:string-join() to recombine the selected context into something that
can be passed to cts:highlight().
We wrote some code to do just that for a publication, and it works well,
but it's a bit messy and could no doubt be optimized and made more
general-purpose. I'd hesitate to post it to the whole list in its
current state--maybe someone out there has an elegant general-purpose
function to do this task--but I can share it offline if you like.

I’m trying to limit the number of words that are displayed for each search

I have been able to get the first paragraph from each document that contains
the search
phrase (responsibility), but I haven’t been able to successfully limit the
words to 7
words before the search phrase and 7 after the phrase. I have looked through
the
cts:search functions, but I haven’t been able to find quite what I’m looking
for. Is
there a function that will help me do this?
Thanks
