Assembly: Lucene.Net.ICU.dll
Syntax
public sealed class ICUCollationDocValuesField : Field, IIndexableField
Remarks

This is more efficient that ICUCollationKeyAnalyzer if the field only has one value: no uninversion is necessary to sort on the field, locale-sensitive range queries can still work via FieldCacheRangeFilter, and the underlying data structures built at index-time are likely more efficient and use less memory than FieldCache.
