q=gold^2.0 ring(boost gold)&defType=dismax would return a document that contains exactly "gold^2.0 ring(boost gold)" in it. dismax is designed to work with simple keyword queries. You can use only three special characters: + - " Rest of the characters, : [ ] ^ ~ etc, don't work. i.e. they are escaped. Please see http://www.lucidimagination.com/blog/2010/05/23/whats-a-dismax/
