C# 클래스 SpellChecker.Net.Search.Spell.SpellChecker

Spell Checker class (Main class)
(initially inspired by the David Spencer code).

Example Usage:

 SpellChecker spellchecker = new SpellChecker(spellIndexDirectory); // To index a field of a user index: spellchecker.indexDictionary(new LuceneDictionary(my_lucene_reader, a_field)); // To index a file containing words: spellchecker.indexDictionary(new PlainTextDictionary(new File("myfile.txt"))); String[] suggestions = spellchecker.suggestSimilar("misspelt", 5);
