Filtering with search-index

I want to implement a full-text-search for *.epub-Files. Therefore I forked the epub-full-text-search module (https://github.com/friedolinfoerder/epub-full-text-search). I will have many ebooks to search through, so I want to have a way to only search in a specific ebook one at a time.

How could I do this with search-index. I coded a solution which allows to search in the fields filename (the unique filename of the epub) and body (the content of the chapters), but this doesn't feel like it's the right way to do this and the performance is also not ideal.

Here is an example how I do the search with search-index:

searchIndex.search({
    query: [{
        AND: [
            {body: ['epub']},
            {filename: ['accessible_epub_3']}
        ]
    }]
});

Is there a better way to do this. Maybe with buckets, categories and filters?

Thanks for your help!

Search-index, which epub-full-text-search is based on, gives one search result back for each document/item that has a match for any given query. My guess is that you would like to know where in the epub-file you get a hit. If a certain paragraph is a good enough search result item, I would index paragraphs. Each paragraph would have a unique book-key as a filter, and maybe a reference to where it is in the epub-file (page/percentage/etc).

Disclaimer: I'm working on the search-index project.
