nLimit |
Maximum number of words to find |

The field to enumerate (the field must have been designated as an EnumerableField when the index was built) |

Remarks
A SearchFilter can be used with ListFieldValues to limit the results to values in a set of documents. Use SetFilter to attach a SearchFilter to the WordListBuilder.
When a SearchFilter is used, all counts returned by WordListBuilder are document counts. For example, if a word occurs 20 times in 7 documents, the count returned will be 7 for both GetNthWordCount and GetNthWordDocCount.
