The SpellingCorrector class is designed to correct spelling errors in search queries, as well as to store words with correct spelling. You can learn about spelling correction in search queries on the Spell checking page.

To get the number of words in the spelling corrector dictionary, use the getCount method.

To get an array of words containing in the spelling corrector dictionary, the getWords method is used.

To add words to the spelling corrector dictionary, use the addRange method.

The clear method is used to remove all words from the spelling corrector dictionary.

To export words to a file, use the exportDictionary method.

To import words from a file, use the importDictionary method.

The following example demonstrates the use of methods of the spelling corrector.

String indexFolder = "c:\\MyIndex\\";
 
// Creating an index from in specified folder
Index index = new Index(indexFolder);
 
if (index.getDictionaries().getSpellingCorrector().getCount() > 0) {
    // Removing all words from the dictionary
    index.getDictionaries().getSpellingCorrector().clear();
}
 
// Adding words to the dictionary
String[] words = new String[] { "achieve", "accomplish", "attain", "reach" };
index.getDictionaries().getSpellingCorrector().addRange(words);
 
// Export words to a file
index.getDictionaries().getSpellingCorrector().exportDictionary("C:\\Words.txt");
 
// Import words from a file
index.getDictionaries().getSpellingCorrector().importDictionary("C:\\Words.txt");
