I am trying to search on MathSciNet for articles which contains $C^*$ in their title (as in $C^*$-algebras) however I can't figure out how to get MathSciNet not to interpret the '*' as a stand in for an arbitrary sequence of characters.

(I am moving this question from [MathStackExcange](http://math.stackexchange.com/questions/1290667/search-for-c-on-mathscinet/1292972#1292972) as no one there seemed to have an answer.)
