The main problem is that you have to pass the precision step and must knwo the
field type of numeric fields before doing a query, else you get wrong results.
We can maybe store the type and precision step in fnx file (like we do for
stored numeric fields in FieldsWriter).
I am not sure whats the best way to do it (without too much code
specialization), but it seems a good idea. On the other hand, we don't store
references to the Analyzer in the fnx file, so why for numeric field (it's just
like an analyzer - if you change it, results are wrong)?
