Class NumericQueryNodeProcessor
This processor is used to convert FieldQueryNodes to NumericRangeQueryNodes. It looks for NUMERIC_CONFIG set in the FieldConfig of every FieldQueryNode found. If NUMERIC_CONFIG is found, it considers that FieldQueryNode to be a numeric query and convert it to NumericRangeQueryNode with upper and lower inclusive and lower and upper equals to the value represented by the FieldQueryNode converted to object representing a .NET numeric type. It means that field:1 is converted to field:[1 TO 1].
Note that FieldQueryNodes children of a IRangeQueryNode are ignored.Implements
