Lazy loading is handled through the FieldSelector interface on
IndexReader.doc() and some variations. There is nothing special that
need be done during indexing to mark a field as lazy. The isLazy
method merely lets you know later, after loading a Document, if the
field is, indeed, lazy. One caveat, lazy fields become undefined if
the underlying IndexReader is closed before accessing the field.
Once a lazy field is loaded, however, this is no longer an issue, as
the field value stays in memory.

I wonder why there is not setter method for the "lazy" member

Field class. Does that mean the propoerty is nominal and setting it

have any effect, or am I missing some point?
Any way, is there any way to tell lucene that a field is to be lazy-
loaded,
from the very beginning of field construction?
