// Load the document
const parser = new groupdocs.Parser("sample.pdf");

// Search for a word page by page
const options = new groupdocs.SearchOptions(false, false, false, true);
const results = parser.search("Lorem", options);

// Print the page index, position and text of every match
const it = results.iterator();
while (it.hasNext()) {
    const result = it.next();
    console.log(`Page ${result.getPageIndex()}, position ${result.getPosition()}: ${result.getText()}`);
}

parser.close();

Extract Images from a Document
