I’m trying to do a text replacement of a small text with a large text where it can automatically re-arrange Page Contents.

content overlap

i m using snapping code below

string DocPath = @“C:\Users\Sumitra.9.Kumar\Desktop\C02_M06_Understanding_Residential_Construction-Structural_Components.pdf”;
Document pdfDocument = new Document(DocPath);
string searchParagraphText = @" such as terminology, shapes, how to distinguish the";
string repParagraphSearch = @“Detail key components of an agreement. this is not working fine at this time.”;
string regSearchText = searchParagraphText.Replace(" “, @”\s*");
Rotation rt;

        foreach (Page page in pdfDocument.Pages)
        {
            rt = page.Rotate;
            page.Rotate = Rotation.None;
            var textFragmentAbsorber = new TextFragmentAbsorber("(?i)(" + regSearchText + ")", new TextSearchOptions(true));
            page.Accept(textFragmentAbsorber);
            TextFragmentCollection textFragmentCollection = textFragmentAbsorber.TextFragments;
            foreach (TextFragment textFragment in textFragmentCollection)
            {
             
                textFragment.Text = repParagraphSearch;
            }
        }
        string newDocPath = @"C:\Users\Sumitra.9.Kumar\Desktop\pdf\C02_M06_Understanding_Residential_Construction-Structural_Components1.pdf"; //New Generate Pdf

Please try to set the TextReplaceOptions like below and let us know in case you still face any issues:

textFragmentAbsorber.TextReplaceOptions = new TextReplaceOptions(TextReplaceOptions.ReplaceAdjustment.WholeWordsHyphenation);

Thanks for Response.
Using this
textFragmentAbsorber.TextReplaceOptions = new TextReplaceOptions(TextReplaceOptions.ReplaceAdjustment.WholeWordsHyphenation);
code Table content overlap and Bullet point also not in proper position .

Here is snapping whole code

Aspose.Pdf.License PdfLicense = new Aspose.Pdf.License();
//// MemoryStream stream = new MemoryStream(File.ReadAllBytes(@“Aspose.PDF.NET.lic”));
PdfLicense.SetLicense(@“Aspose.PDF.NET.lic”);
Console.WriteLine(“Replacing Process continue , now check new Generated PDF”);
string DocPath = @“C:\Users\Sumitra.9.Kumar\Desktop\CitationNeededBook-Sample.pdf”;
Document pdfDocument = new Document(DocPath);
string searchParagraphText = @“Residential Lot Styles and Features”;
string repParagraphSearch = @“Detail key components of an agreement of purchase and sale for an industrial property”;
string regSearchText = searchParagraphText.Replace(" “, @”\s*");
Rotation rt;

        foreach (Page page in pdfDocument.Pages)
        {
            rt = page.Rotate;
            page.Rotate = Rotation.None;
            var textFragmentAbsorber = new TextFragmentAbsorber("(?i)(" + regSearchText + ")", new TextSearchOptions(true));
            textFragmentAbsorber.TextReplaceOptions = new TextReplaceOptions(TextReplaceOptions.ReplaceAdjustment.WholeWordsHyphenation);
            page.Accept(textFragmentAbsorber);
            TextFragmentCollection textFragmentCollection = textFragmentAbsorber.TextFragments;
            foreach (TextFragment textFragment in textFragmentCollection)
            {
                textFragment.Text = repParagraphSearch;
            }
        }
        string newDocPath = @"C:\Users\Sumitra.9.Kumar\Desktop\pdf\CitationNeededBook-Sample.pdf"; //New Generate Pdf
