Synonym dictionary

The SynonymDictionary class is designed to store synonyms in an index. For information on searching using synonyms, see the Synonym search page.

To get the number of synonyms in the dictionary, use the getCount method.

To add groups of synonyms to the dictionary, use the addRange method.

The clear method is used to remove all synonyms from the dictionary.

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

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

The following example demonstrates the use of methods of the synonym dictionary.

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