You'd like to find keywords in pdf,doc files using ASP.NET, isn't it? You could extract text from various document types, then you could search the word in the text. Please Check the following thread.

I hope it's helpful to you.

hi Srvna,

After searching on google, I found a solution of finding and highlighting word in Word document using VB.NET, refer following code:

Shared Sub Main(ByVal args() As String)
            'Create Document
            Dim document As New Document()
            document.LoadFromFile("E:\Work\Documents\WordDocuments\References.docx")

            Dim text() As TextSelection = document.FindAllString("forming", False, True)
            For Each seletion As TextSelection In text
                seletion.GetAsOneRange().CharacterFormat.HighlightColor = Color.Yellow
            Next seletion

            document.SaveToFile("FindHighlight.docx", FileFormat.Docx)
            System.Diagnostics.Process.Start("FindHighlight.docx")
End Sub

for further information, you can refer this article:

As far as I know, it's a .NET word library and it has a free version, check here:
