I prefer option #4 myself. Also note that a similar issue with
patches exists within JIRA:
<https://issues.apache.org:443/jira/browse/LUCENE-509>

OK, how about a vote on this.
I see several ways of implementing the front end to this:
1. Declarative: On construction of a Document, you declare the
Field to be Lazy.
2. Implicit: All fields are Lazy
3. Size of Field. Pass into IndexReader.document() the size of the
field above which it will be lazily loaded. A default size can
also be used.
4. By Field name. Pass in the names of the Fields that you want
loaded lazily.
Thanks,
Grant

My main concern is the semantics of the fieldsStream and whether
that would be closed behind the back of the LazyField
implementation. My understanding is that as long as the
IndexReader is open, this stream should also be open. Is that
correct? What am I forgetting about?
You need to make sure that access to the stream is synchronized,
so that one thread doesn't move the file pointer while someone
else is reading. You could use a cloned stream in a ThreadLocal
to avoid contention.
