Thank for fast reply and clarification, I also would like to ask about indexing without storing. We have document like this: - title - newspaper - <url to pdf in /binaries> And now we need ability to search documents that have some text in pdf. I want to to this by writing my extractor that will take pdf, extract text and put it in property. As you said before this is the way it should be done. But in this case its completely unnesesary to keep pdf's text. Is there a way to avoid duplication?
