public byte[] binaryValue()
The value of the field in Binary, or null. If null, the Reader value,
String value, or TokenStream value is used. Exactly one of stringValue(),
readerValue(), binaryValue(), and tokenStreamValue() must be set.

 public float getBoost()
Returns the boost factor for hits for this field.

The default value is 1.0.

Note: this value is not stored directly with the document in the index.
Documents returned from org.apache.lucene.index.IndexReader#document(int)  and
org.apache.lucene.search.Hits#doc(int)  may thus not have the same value present as when
this field was indexed.

 public boolean getOmitNorms()
True if norms are omitted for this indexed field

 public boolean isBinary()
True iff the value of the filed is stored as binary

 public boolean isCompressed()
True if the value of the field is stored and compressed within the index

 public boolean isIndexed()
True iff the value of the field is to be indexed, so that it may be
searched on.

 public boolean isLazy()
Indicates whether a Field is Lazy or not. The semantics of Lazy loading are such that if a Field is lazily loaded, retrieving
it's values via #stringValue()  or #binaryValue()  is only valid as long as the org.apache.lucene.index.IndexReader  that
retrieved the Document  is still open.

 public boolean isStoreOffsetWithTermVector()
True iff terms are stored as term vector together with their offsets
(start and end positon in source text).

 public boolean isStorePositionWithTermVector()
True iff terms are stored as term vector together with their token positions.

 public boolean isStored()
True iff the value of the field is to be stored in the index for return
with search hits. It is an error for this to be true if a field is
Reader-valued.

 public boolean isTermVectorStored()
True iff the term or terms used to index this field are stored as a term
vector, available from org.apache.lucene.index.IndexReader#getTermFreqVector(int,String) .
These methods do not provide access to the original content of the field,
only to terms used to index it. If the original content must be
preserved, use the stored attribute instead.

 public boolean isTokenized()
True iff the value of the field should be tokenized as text prior to
indexing. Un-tokenized fields are indexed as a single word and may not be
Reader-valued.

 public String name()
Returns the name of the field as an interned string.
For example "date", "title", "body", ...

 public Reader readerValue()
The value of the field as a Reader, or null. If null, the String value,
binary value, or TokenStream value is used. Exactly one of stringValue(),
readerValue(), binaryValue(), and tokenStreamValue() must be set.

 public  void setBoost(float boost)
Sets the boost factor hits on this field. This value will be
multiplied into the score of all hits on this this field of this
document.

The boost is multiplied by org.apache.lucene.document.Document#getBoost()  of the document
containing this field. If a document has multiple fields with the same
name, all such values are multiplied together. This product is then
multipled by the value org.apache.lucene.search.Similarity#lengthNorm(String,int) , and
rounded by org.apache.lucene.search.Similarity#encodeNorm(float)  before it is stored in the
index. One should attempt to ensure that this product does not overflow
the range of that encoding.

 public  void setOmitNorms(boolean omitNorms)
Expert:

If set, omit normalization factors associated with this indexed field.
This effectively disables indexing boosts and length normalization for this field.

 public String stringValue()
The value of the field as a String, or null. If null, the Reader value,
binary value, or TokenStream value is used. Exactly one of stringValue(),
readerValue(), binaryValue(), and tokenStreamValue() must be set.

 public TokenStream tokenStreamValue()
The value of the field as a TokenStream, or null. If null, the Reader value,
String value, or binary value is used. Exactly one of stringValue(),
readerValue(), binaryValue(), and tokenStreamValue() must be set.
