form handling and query syntax

I'm looking to use SOLR to replace the search components of a Lucene-based application I built a few years ago. One bit of functionality that I'm not seeing is how to handle form input and translate it to Lucene QueryParser syntax to pass into the SOLR servlet. An example of the kind of searc
