Improving search relevance takes time and iterative refinement.

The LucidImagination team have a good write up (very solr based though): http://www.lucidimagination.com/Community/Hear-from-the-Experts/Articles/Search-Application-Relevance-Issues

You may want to analyse logs and add pageviews per doc into your index so you can factor that in your sort order.

The figures don't have to be really accurate as long as magnitude variations are captured.

You should also analyse logs for mis-spellings. The lucidimagination guys had some a podcast or blog about indexing them as well.
