The default serializer is a simple one that handles top-level fields, but does not render collections or nested objects. The index has an associated serializer that renders the indexed object as a Lucene document comprised of searchable fields. When no analyzer is specified, the .standard.StandardAnalyzer is used. _REGION_VALUE_FIELD serves as the field name for entry values of all primitive types, including String, Long, Integer, Float, and Double.Įach field has a corresponding analyzer to extract terms from text. If the object value for the entries in the region comprises a primitive type value without a field name, then use _REGION_VALUE_FIELD to specify the field to be indexed. You must specify at least one field to be indexed.
