Class Field.Index

class
Field.Index
extends Parameter
implements Serializable
Specifies whether and how a field should be indexed.
Do not index the field value. This field can thus not be searched,
but one can still access its contents provided it is
{@link Field.Store stored}.
Index the field's value without an Analyzer, and disable
the storing of norms. No norms means that index-time boosting
and field length normalization will be disabled. The benefit is
less memory usage as norms take up one byte per indexed field
for every document in the index.
Index the field's value so it can be searched. An Analyzer will be used
to tokenize and possibly further normalize the text before its
terms will be stored in the index. This is useful for common text.
Index the field's value without using an Analyzer, so it can be searched.
As no analyzer is used the value will be stored as a single term. This is
useful for unique Ids like product numbers.
