I'm not sure I understand your question. The number of documents
has no bearing on the field length of each, which is what the
max field length is all about. You can change the value here
by calling Indexwriter.setMaxFieldLength to something shorter
than the default.

So no, if no document exceeds the default (Terms, not characters),
no document will be truncated.

The 10,000 limit also has no bearing on how much space indexing
a document takes as long as there are fewer then 10,000 terms. That
is, a document with 5,000 terms will take up just as much space
with any MaxfieldLength > 5,000.
