createField

public IndexableField createField(SchemaField field,
                         Object val,
                         float boost)

Description copied from class: FieldType

Used for adding a document when a field needs to be created from a type and a string.

By default, the indexed value is the same as the stored value (taken from toInternal()). Having a different representation for external, internal, and indexed would present quite a few problems given the current Lucene architecture. An analyzer for adding docs would need to translate internal->indexed while an analyzer for querying would need to translate external->indexed.

The only other alternative to having internal==indexed would be to have internal==external. In this case, toInternal should convert to the indexed representation, toExternal() should do nothing, and createField() should *not* call toInternal, but use the external value and set tokenized=true to get Lucene to convert to the internal(indexed) form.

:TODO: clean up and clarify this explanation.

Overrides:

createField in class FieldType
