Get the number of documents in which this word occurs

public long GetNthWordDocCount(long whichWord);

Public Function GetNthWordDocCount(whichWord As long) As long

Number of documents in which this word occurs. 

Note: To make WordListBuilder fast, it does not actually enumerate all of the references for each word, so in some cases the count can include artifacts of the indexing process such as removed or reindexed documents, which can make the reported count higher than the actual count in the index. Compressing an index will eliminate these extra references.
