The problem can possibly be related to the regular expressions. Can you please share the sample PDF and the text that you want to highlight in it? We will try to add the highlight annotation over it in our environment and share our feedback with you accordingly.

We are trying to search for the below paragraph and annotate it.

“We have audited the accompanying financial statements of (the “Company”), which comprise the balance sheets as
of December 31, 2019 and 2018, and the related statements of operations, changes in members’ (deficit)/equity and
cash flows for the years then ended, and the related notes to the financial statements.”

Please let me know if you have any further questions on this. Appreciate your help.

You can use the next code snippet to get the necessary result:

String inputText = "We have audited the accompanying financial statements of (the \"Company\"), which comprise the balance sheets as of December 31, 2019 and 2018, and the related statements of operations, changes in members' (deficit)/equity and cash flows for the years then ended, and the related notes to the financial statements.";

String regexText = escapeRegex(inputText).replaceAll(" ", "\\\\s+");
Document document = new Document(dataDir + "inputforhighlight.pdf");
Page page = document.getPages().get_Item(3);
TextFragmentAbsorber tfa = new TextFragmentAbsorber(regexText, new TextSearchOptions(true));
tfa.visit(page);
for (TextFragment textFragment : tfa.getTextFragments()) {
    System.out.println("Found Text!!");
    HighlightAnnotation highlightAnnotation = new HighlightAnnotation(textFragment.getPage(), textFragment.getRectangle());
    page.getAnnotations().add(highlightAnnotation);
}
document.save(dataDir + "inputforhighlight_mod_" + BuildVersionInfo.AssemblyVersion + ".pdf");

private static String escapeRegex(String input) {
    return input.replaceAll("([\"\'.*+?{}()\\^$|])", "\\\\$1");
}
