[Egothor-tech] Grouping search result

[ekirin]

Hello to all!
I'm a newcomer. And look closely at Egothor search engine. Sorry if I
duplicate the question. I'm wonder can I
grouping my search result with Egothor. As example: suppose I've got a
set of books and when I do a search then get a search result like this:
------------------
1. bookName:
     ChapterName
     text from chapter
2. bookName:
     ChapterName
     text from chapter
------------------
If Egothor does not support this feature. Is it difficut to
add to Egothor? How do you think?

Thanks for your responses!
