C# Class Lucene.Net.QueryParsers.Flexible.Standard.Processors.NumericQueryNodeProcessor

This processor is used to convert FieldQueryNodes to NumericRangeQueryNodes. It looks for ConfigurationKeys.NUMERIC_CONFIG set in the FieldConfig of every FieldQueryNode found. If ConfigurationKeys.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 RangeQueryNode are ignored.
