Unknown query type 'edismax'

[Swapnonil Mukherjee]

Hi,

I just downloaded apache-solr-1.4.1 and am trying to run an edismax query using 
the defType argument as edismax.

But I am setting an Unkown query type exception.

Do I need to make any changes to solrconfig.xml to get edismax queries to work?
