> When loading field from the index without a FieldSelector, and often in user code we know exactly how many fields a Document should have. This patch will simply add the ability to allocate Document memory for precisely.
> I will include as a separate patch where this would be useful in conjunction with patch [LUCENE-2276|https://issues.apache.org/jira/browse/LUCENE-2276].
