Hi,
I have an index which I generated with clucene where there is a float field.
This float field is stored as a simple verbatim character string.
The solr schema doc states that for such float fields:
 <!-- numeric field types that store and index the text
        value verbatim (and hence don't support range queries, since the
        lexicographic ordering isn't equal to the numeric ordering) -->

And for sortable float fields:
<!-- Numeric field types that manipulate the value into
        a string value that isn't human-readable in its internal form,
        but with a lexicographic ordering the same as the numeric ordering,
        so that range queries work correctly. -->

What does exactly means 'a string value that isn't human-readable in
its internal form' ?
Does that mean that such a field as to be indexed as a binary
representation of the number to allow the use of the sfloat type ?

I noticed that in the FloatField class, the method getSortField is like that:

public SortField getSortField(SchemaField field,boolean reverse) {
   return new SortField(field.name,SortField.FLOAT, reverse);
 }

It seems to return the right type of SortField.FLOAT adapted to my field.

In SortableFloatField,
 public SortField getSortField(SchemaField field,boolean reverse) {
   return getStringSort(field,reverse);
 }

I'm not sure to understand all of this,

but what I feel is that since the type 'FloatField' gives that  'new
SortField(field.name,SortField.FLOAT)' , it should suits my verbatim
float data for sorting the query results.

Do I have the right feeling ?

thanks for your help
