How could we link the Entity Candidates to their Surface From in query?

If you call the following method getResults in the following class, you would see EntityResult object being returned. EntityResult has a field named Span which can give you offset with respect to the input text.

I was about to ask that. Thanks!

A quick follow-up: I'm wondering if it's possible to do the same for coherentEntityLinker. Here is what i'm currently at:

changed EntityResult to add a Span variable
including variable in the map as such:

List<EntityResult> candidates = felCandidates.stream().map(felResult -> {
        String wikiId = ...;
        return new EntityResult(wikiId, felResult.score, felResult.type, felResult.s);

but the Span variable seems to hold the entire query, instead of only the surface form. Is it the expected behaviour? Or is there a step I'm missing?

Thanks!
