hello,
i am using lucene 4.6. in my query i use a collector to get field values.
setNextReader is implemented as below.
public void setNextReader(AtomicReaderContext context) throws IOException {
cacheIDs = FieldCache.DEFAULT.getInts(context.reader(), "id", true);
}
and collect
public void collect(int docnr) throws IOException {
int id = 0;
id = cacheIDs .get(docnr);
...
}
But sometimes i got an exception like
2015-01-12 13:32:49,342 [ID:1e8e1dff-9a57-11e4-a697-c29020524153]ERROR

when i try to get the field the normal way like this
Document doc = reader.document(docnr);
String sid = doc.get("id");
int id = Integer.parseInt(sid);
everything is fine.
am i doing something wrong?
regards
Sascha
