Issue with view mode for search results

Problem/Motivation

For my search results, I want to show an excerpt that includes the search term in the content. Right now, it is only showing a preview of the actual page content (the title and body) but does not include the search term anywhere.
I can't figure out how to do this. I tried going to Format->Show->Settings and selecting Teaser and Search Result but neither of those options work.

Steps to reproduce

Go here: https://test.bostonmpo.org/search/content
Type in "Betsy"
The results are all pages with "Betsy" keyword but the search results do not show any excerpt with the keyword

Proposed resolution

Does anyone know a solution that does not involve coding? I am new to this module I used to use the standard search so this is very complex for me.
