Unable to search the text begins special character and Multiline in the pdf

Hi Team,

We are unable to search for the string in pdf starts with special character and multiline text.

TextSearchOptions op1 = new TextSearchOptions(false);

op1.UseFontEngineEncoding = true;
op1.IgnoreResourceFontErrors = true;
op1.SearchForTextRelatedGraphics = false;
op1.IgnoreShadowText = true;

//op1.

TextFragmentAbsorber textFragmentAbsorber = new TextFragmentAbsorber(citation.CitationText, op1);

textFragmentAbsorber.ExtractionOptions.FormattingMode = TextExtractionOptions.TextFormattingMode.Pure;

document.Pages[citation.ReportPageNumber].Accept(textFragmentAbsorber);

Please help me on this.

Thanks,
Rajesh
