Build solrj query programmatically

Question

I need to build solr queries programmatically based on user selections. e.g. if the user select a checkbox I add a clause, if they choose a dropdown I add another clause etc.

As I understand it solr simply accepts a string for the "q" param so I was thinking to use lucene's query builder to build the query then call toString(). It seems like a hack but I can't think of a better solution. Has anyone else done this before? Is there a better approach?
