There is open source library called iTextSharp.

You can just upload CV and place it on server at specific path then you can read it's contents in string and see whether your text exist there as below.

public bool KeywordExists(string keyWord)
{
    using (PdfReader reader = new PdfReader(pdfPath))
    {
        StringBuilder strText = new StringBuilder();    
        for (int i = 1; i <= reader.NumberOfPages; i++)
        {
            strText.Append(PdfTextExtractor.GetTextFromPage(reader, i));
            if(strText.Contains(keyWord)) return true;
        }
        return false;
     }
}
