Highlight Fragment location

Elastic Stack Elasticsearch
1

I'm highlighting 100 character fragments on a relatively small text field,
~2,000 characters.

Is it possible to know if the highlighted fragment contains the start of
the document? The use case is displaying "..." before the fragment if it's
not the start of the document.

Thanks for any help!

You could simply compare the search query with the start of the start of
the document? Or are you looking for some other way?

Hmm, I would first have to strip the highlight tags. That doesn't sound
ideal. I wonder if the highlighter could just return the indexes of the
fragment inside the field.

Maybe this isn't a common use case.

I think that you should ask for a feature request in github :
something like : prefix and suffix for highlight parts (with default =null)

Set the tags to empty strings and then you'll have the frag without and
highlighting.
Alternatively, use very simple tags, it doesn't have to be HTML.
But I wouldn't worry about playing with a few string fragments. To get
that fragment ES probably dealt with 1000s of them.
