below sample code is used to search the text, If text content has two or more paragraph content then no text fragment in the list.

var tfa = new TextFragmentAbsorber(new Regex(textContent.Trim().Replace(" ", @"\s*").Replace("(", @"\(").Replace(")", @"\)").Replace(".", @"\.").Replace(":", @"\:").Replace("-", @"\-").Replace(' ', ' ').Replace("", "")), new TextSearchOptions(true));                    
                    TextSearchOptions textSearchOptions = new TextSearchOptions(true);
                    tfa.TextSearchOptions = textSearchOptions;

We are assuming that you are copying all text from the PDF and assigning it to the textContent variable. Right?

Yes, I will get the text content from html. thus html is converter to Pdf at first.

i.e string textContent = element.TextContent;

finding that text content in PDF. for single para, single word its working but for mutiple para is not searching.

we have checked for this problem but could not find it. Please check your regular expression to search the text. Note that you can search the entire text of the document and try to find any result using your regular expression. As you can see, TextFragmentAbsorber returns all the text from the page, but there are no results that could be based on your regular expression. Take a look at the following code snippet.

var input = GetInputPath("57723.pdf");
string textContent = @"The Directors recognise that the strength of our business is built on the hard work, loyalty, dedication
and abilities of all of our people. The success of our business depends on attracting, retaining, and
motivating employees. Ensuring that we remain a responsible employer, from pay and benefits to our health, safety and
workplace environment, the Directors' factor the implications of decisions on employees and the wider
workforce where relevant and feasible.";
Document pdfDocument = new Document(input);
var tfa = new TextFragmentAbsorber();
pdfDocument.Pages.Accept(tfa);
var rx = new Regex(textContent.Trim().Replace(" ", @"\s*").Replace("(", @"(").Replace(")", @")")
.Replace(".", @".").Replace(":", @":").Replace("-", @"-").Replace(' ', ' ').Replace("", ""));
var matches = rx.Matches(tfa.Text).Count;
