Method SetNorm

SetNorm(Int32, String, Byte)

Expert: Resets the normalization factor for the named field of the named document. The norm represents the product of the field's Boost and its length normalization. Thus, to preserve the length normalization values when resetting this, one should base the new value upon the old.

NOTE: If this field does not store norms, then this method call will silently do nothing.

Declaration
public virtual void SetNorm(int doc, String field, byte value)
Parameters
Type Name Description
System.Int32 doc
String field
System.Byte value
Exceptions
Type Condition
StaleReaderException

If the index has changed since this reader was opened

If the index is corrupt
LockObtainFailedException

If another writer has this index open (write.lock could not be obtained)
