// Creating a document object
InputStream stream = new FileInputStream(documentFilePath);
Document document = Document.createFromStream(documentFilePath, new Date(), ".pdf", stream);
Document[] documents = new Document[] {
    document,
};
 
// Indexing document from the stream
IndexingOptions options = new IndexingOptions();
index.add(documents, options);
 
// Closing the document stream after indexing is complete
stream.close();
