Subject Re: Field Boosting with q.alt parameter Query
Date Wed, 04 Mar 2009 07:07:36 GMT

Hi Eric,

Thanks for all the inputs you have given. They are really helpful. I am able
to achieve the field boosting * wildcard with dismax. For this, I had to
make code changes in DisjunctionMaxQueryParser sub class in SolrPluginUtils
class.

Thanks,
Amit Garg
