Can anyone tell, how to display pdf file on web with search text functionality.

• c#
• asp.net
• .net

If you mean searching inside the pdf files, you can do this:

• download this dll Interop.Cisso.DLL and then add it as a reference
• Create your catalog (you should define a catalog in the indexing service to search inside it) it is done this way: http://support.microsoft.com/kb/308202

• finally here is your code for doing the search:

     DataSet ds = new DataSet("IndexServerResults");
      CissoQueryClass q = new CissoQueryClass();
      CissoUtilClass util = new CissoUtilClass();
  
      OleDbDataAdapter da = new OleDbDataAdapter();
  
  string query = "";
  if (lstSearchIntegration.SelectedValue == "-1") {
      query = "@all Contains " + txtKeywordOne.Text + " and not #filename *.log";
  } else {
      string operation = "";
      if (lstSearchIntegration.SelectedValue.ToLower == "and") {
          operation = "and";
      } else {
          operation = "or";
      }
      query = "@all Contains " + txtKeywordOne.Text + " " + operation + " " + txtKeywordTwo.Text;
  
   }
  
  switch (lstDocType.SelectedValue) {
      case "doc":
          query += " and #filename *.doc";
          break;
      case "pdf":
          query += " and #filename *.pdf";
          break;
      case "ppt":
          query += " and #filename *.ppt";
          break;
      case "pps":
          query += " and #filename *.pps";
          break;
  }
  
  q.Query = query;
  q.Catalog = "YourCatalogName";
  q.SortBy = "rank[d]";
  q.Columns = "DocAppName,rank, path, size, FileName,VPath, Create";
  
  q.MaxRecords = 1000;
      util.AddScopeToQuery(q, "YourFolder", "deep");
  object obj = q.CreateRecordset("nonsequential");
  da.Fill(ds, obj, "IndexServerResults");
  DataTable mydt = new DataTable();
  mydt = ds.Tables[0];
  

Please note that:

1. I am using and/or operations for smarter search
2. I am searching inside doc,pdf,ppt and pps
3. I am excluding log files from search

I can suggest Aspose.PDF but it costs money
