Prepare doc and docx Files for Lucene indexing

Question

I wanted to ask if there is a quick way of getting content of a document into a single document field. All the examples i have seen have relatively short strings. I cannot save an entire journal article into a string and indexthat is there a quick way of telling lucene to index all the words in a file? I am using Lucene.net 3.03 for this application.

Could use iFilter to extract words. You get words with no formatting. Paid there is Aspose for formatted text. — paparazzo, Feb 13 '13 at 18:04
What is the format of the document and what do you mean by journal article? — paparazzo, Feb 13 '13 at 20:27

There is not an easy way to pass just the file, you have to provide the entire content to lucene to made the indexing for the search. Here is a answer from the Q/A about indexing PDF, but is the same from every type of document, just open it and index to lucene.

You can just pass a System.IO.TextReader to a Field. If the file is plain text, or something like it, you should just be able to open the Reader on it, and pass it directly into the Field, like:

System.IO.TextReader reader = new StreamReader("path/to/my/file.txt");
Field field = new Field("fieldName", reader);
document.add(field);

I like this idea!!! Are readers availabe in C# if so what namespace do I need to reference? – TheCodeNovice Feb 13 '13 at 18:21
That's my best shot at the C# version. Not really a C# dev, to be honest, so if I messed something up, please feel free to edit. – femtoRgon Feb 13 '13 at 20:21
