No. setFields is equvalent to  &fl=title,description  It determines which fields will
be returned as a result.

SolrQuery extends ModifiableSolrParams. If you look at the source code of it you can understand.
For example setQuery method invokes this.set(CommonParams.Q, query);

You can set anything in the search url with this class. &key=value is equal to SolrQuery.set(key,
value). There are some multivalued keys like fq and facet.field, in those cases you can use
add() method.
