Subject RE: NPE inside org.apache.lucene.index.SegmentReader.getNorms
Date Wed, 03 Dec 2008 18:39:40 GMT
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?
