Search & Index Documents using Node.js API

// Create an index
const index = new Index('c:/IndexFolder');
index.add('c:/DocumentFolder');

// Set up search options
var options = new SearchOptions();
options.getFuzzySearch().setEnabled(true);
options.getFuzzySearch().setFuzzyAlgorithm(new TableDiscreteFunction(3));

// Search for documents containing the word 'water' or the phrase 'Lorem ipsum'
var query = "water OR \"Lorem ipsum\"";
var result = index.search(query, options);

// Process search result
console.log("Documents: " + result.getDocumentCount());
console.log("Total occurrences: " + result.getOccurrenceCount());
for (int i = 0; i < result.getDocumentCount(); i++) {
    FoundDocument document = result.getFoundDocument(i);
    console.log('Document: ${document.getDocumentInfo().getFilePath()}');
    console.log('Occurrences: ${document.getOccurrenceCount()}');
    }

// Create an index
const index = new Index('c:/IndexFolder');
index.add('c:/DocumentFolder');

// Search for the phrase in text form

// The first caret character at the beginning indicates that this is a regular expression search query
var query = "^^(.)\\1{1,}";
// Search for two or more identical characters at the beginning of a word
var result = index.search(query);
