C# Class Lucene.Net.Search.FuzzyTermsEnum.AutomatonFuzzyTermsEnum

Implement fuzzy enumeration with Terms.intersect.

this is the fastest method as opposed to LinearFuzzyTermsEnum: as enumeration is logarithmic to the number of terms (instead of linear) and comparison is linear to length of the term (rather than quadratic)

Inheritance: FilteredTermsEnum
