Actually I think something "outside" Lucene is probably setting that
field.
How did you create the Query that you are searching on?

Hello again,
A debugging session shows that
SpanWeight.query.field is null when SpanWeight.scorer() is being
executed.
API doc says getField() is to "Returns the name of the field matched
by this query."
Am I right to assume that this field is set by a search mechanism
within Lucene,
not by my code?

Is there any known Lucene bug that might cause this?
I'm using Lucene 2.1.0.
