# Description
IndexSortSortedNumericDocValuesRangeQuery unconditionally assumes the usage
of the LONG-encoded SortField. Using the numeric range query (in case of sorted
index) with anything but LONG ends up with class cast exception.
```
> java.lang.ClassCastException: class java.lang.Long cannot be cast to
class java.lang.Integer (java.lang.Long and java.lang.Integer are in module
java.base of loader 'bootstrap')

# Solution
The `IndexSortSortedNumericDocValuesRangeQuery` should consult the numeric
type of the `SortField` and perform appropriate conversions.
# Tests
Added the test cases for LONG / INT / FLOAT / DOUBLE fields.
