Q:

Sitecore Advanced Database Crawler numeric dynamic fields

With ADC / scSearchContrib, is it possible for a dynamic field to be treated as numeric in lucene?

A:

Looking at the NumberFieldCrawler class in the scSearchContrib solution has led to me the answer I think.
it contains the following code which seems to be what Lucene needs.
 long value;

 if (!String.IsNullOrEmpty(_field.Value) && long.TryParse(_field.Value, out value))
 {
     return NumberTools.LongToString(value);
 }
