Unable to search the "$450" from a pdf using attach code

I have used to the below code search the text from pdf and we are unable to get a result for a text which contains “$” symbol. Can you help us on that.

TextSearchOptions op1 = new TextSearchOptions(true);
op1.UseFontEngineEncoding = true;
op1.IgnoreResourceFontErrors = true;
op1.SearchForTextRelatedGraphics = false;
op1.IgnoreShadowText = true;

string searchText = searchString.Replace(" “, @”\s*“).Replace(”\n", @“\s*”);
//searchText = searchText.Replace(“(”, @“(”).Replace(“)”, @“)”);
//searchText = searchText.Replace(“[”, @“[”).Replace(“]”, @“]”);
//searchText = searchText.Replace(“?”, @“?”).Replace(“+”, @“+”);
searchText = searchText.Replace(“$”, @“”);
// searchText = searchText.Replace(“-”, @“-”).Replace(“^”, @“^”);
// searchText = searchText.Replace(“{”, @“{”).Replace(“}”, @“}”);
//searchText = searchText.Replace(“|”, @“|”).Replace(“*”, @“*”);

TextFragmentAbsorber textFragmentAbsorber = new TextFragmentAbsorber(searchText, op1);

document.Pages[1].Accept(textFragmentAbsorber);

Below is the simple code snippet that we used with 24.10 version of the API and could not replicate the issue:

Aspose.Pdf.Document pdfDocument = new Aspose.Pdf.Document(dataDir + "Test PDF for verifcation.pdf");

// Create TextAbsorber object to find all instances of the input search phrase
TextFragmentAbsorber textFragmentAbsorber = new TextFragmentAbsorber("$450");
// Accept the absorber for all the pages
pdfDocument.Pages.Accept(textFragmentAbsorber);

Would you please try this way and let us know if issue still persists?
