Search for on blog "paris" return "comparison"

I have this site set up with WordPress:
https://fashioncow.topheavypilesofbooks.com/
If you search for the term “paris”, the first item returned is a post containing the word “comparison”. Paris is not in the post. Is there a way to fix this?

The theme does contain a search.php template with a single bare-bones loop, i.e the query is:<?php if (have_posts()) : while (have_posts() ) : the_post(); ?>
