Thank you Shawn, this pretty much does what I need it to do:
select?defType=edismax&q={!q.op=OR}search_field:term1 term2&pf=search_field

I'm reviewing the Edismax page now. Is there any other documentation
that I should review? I have found the Edismax page at the wonderful
lucidworks site, but if there are any other documentation that I
should review to squeeze the most out of Edismax thenI would love to
know about it.

Thank you very much!
