Confluence API randomly giving "E" and "current" in search results

When searching using our Confluence API for terms like “Lucas”, the results generated include Lucas, but also highlight “E” in standalone results as well as results including Lucas. Even though there is no “E” in the search term, “E” is being highlighted by the API. This is the case in many searches such as “test”, “working” also highlights the word “current” on occasion as well. In short, our confluence API is returning irrelevant results primarily “E” and “current” when neither are remotely close to the search term.
