@bharathiGK,

Please share sample PDF file, console application and the output HTML. In your screenshots, looking at the evaluation mark, we noticed that you are also using GroupDocs.Parser for .NET, is that so?
Secondly, as per your screenshots, you are performing search over Word documents but you mentioned in query that PDF is being used, highlighted and saved as HTML.

Hi…i will attach the original documents.

@bharathiGK,

Please compress HTML file to zip format and then try to upload.

@bharathiGK,

If I am not wrong, you want to search for a keyword/text in the source document and get a HTML output with highlighted text but the output HTML must follow the source file formatting.
We are investigating this scenario. Your investigating ticket ID is SEARCHNET-2270. As there’s any update, you’ll be notified.

Hi.Any Update on this?.when can i expect solution for this.

@bharathiGK

We’ve improved the text extraction in terms of format in API version 20.6. Have a look at the code below:

string indexFolder = @"c:\MyIndex";
string documentFolder = @"c:\MyDocuments";
IndexSettings settings = new IndexSettings();
settings.UseRawTextExtraction = false;
// Creating an index
Index index = new Index(indexFolder, settings);
// Indexing documents in the document folder
index.Add(documentFolder);
