Erick, Thank you for your response to my concerns! After reading some documentations, I come up with the following "solution." It is not doing exactly what I would like it to do, but close.
Basically I set hl.snippets to be a large int, e.g. 50, and hl.fragsize a small positive int, e.g. 1. The parameter hl.snippets defines the maximum number of highlight snippets returned, and hl.fragsize defines the number of characters in each returned snippet. By setting hl.snippets=50&hl.fragsize=1, I can get a list of highlight snippets. Each snippet will include mainly the matched query words with a couple other words before or after the matched words. At least, the regex will have an easier job to do. It is simply a workaround before a formal solution can be found. I will post more information after I dig deeper in the issue.

The regex shouldn't be all that expensive, do you have proof that this is a performance issue? If you don't, I'd just do the simple thing first... And probably just searching for <em> would be better than REs....
