In that case, the behavior is not defined, it might throw an exception or return a random value. You should make sure you always call this method with a valid document ID. > 2. the doc with this docID is already deleted It will return the same value it returned prior to the document deletion. However, you shouldn't rely on this. > 2. the doc with this docID doesn't has the field In that case, the behavior is defined: it will return 0. Numeric doc values expect are dense: all documents have a value. When a document doesn't have a value, 0 will be assigned by default at indexing time. -- Adrien --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org
