How to compose a query from multiple HTTP URL parameters?

[Conal Tuohy]

I would like to be able to specify a query over multiple fields using 
just an HTML form with different parameters for the different fields.

Is it possible to configure Solr to accept a URL of this form:
select?Species=Pseudonaja+textilis&Hospital=Griffith+Base+Hospital

... instead of:

q=Species:'Pseudonaja+textilis'+Hospital:'Griffith+Base+Hospital'

I have read some information about parameter indirection or parameter 
dereferencing, but I haven't been able to get it to work.
