C# Класс Lucene.Net.Search.FuzzyTermsEnum

Subclass of TermsEnum for enumerating all terms that are similar to the specified filter term.

Term enumerations are always ordered by #getComparator. Each term in the enumeration is greater than all that precede it.

Наследование: TermsEnum

FuzzyTermsEnum() публичный Метод

Constructor for enumeration of all terms from specified reader which share a prefix of length prefixLength with term and which have a fuzzy similarity > minSimilarity.

After calling the constructor the enumeration is already pointing to the first valid term if such a term exists.

if there is a low-level IO error
