Class IcuCollationDocValuesField

java.lang.Object

org.apache.lucene.document.Field

org.xbib.elasticsearch.index.analysis.icu.IcuCollationDocValuesField

All Implemented Interfaces:

org.apache.lucene.index.IndexableField

public final class IcuCollationDocValuesField
extends org.apache.lucene.document.Field

Indexes collation keys as a single-valued SortedDocValuesField. This is more efficient that IcuCollationKeyAnalyzer if the field only has one value: no un-inversion is necessary to sort on the field, locale-sensitive range queries can still work via DocValuesRangeQuery, and the underlying data structures built at index-time are likely more efficient and use less memory than FieldCache.
