Solving a search query is an eval, but I think you are saying you 
want to avoid code injection which is fair enough.

Off the top of my head you can map over the sexpr returned by read 
and rewrite the symbols to ones you control before evaling.

In my opinion it is still worth avoiding a parse, which is what 
Lisp can give you.
