No. :)

When the query parser find something which looks like a range, each 
ValueRangeProcessor is called (in the order they're added to the query 
parser) and can decide to accept the range (in which case it returns the 
start and end values, so it can do marshalling to make the values into 
fixed-width number representations, for example), or reject the range, 
in which case the next processor is called.

So, you could have a date range processor, which accepts ranges which 
look like dates, and a numeric processor, which accepts ranges which don't.
