How large are your documents? Looks like [highlighting with large documents can be slow](https://discuss.elastic.co/t/query-string-with-highlighting-slow-and-high-cpu-usage/123790/7).

Are you looking for a way to turn highlighting off? You can do this by navigating to `Management` =\> `Advanced Settings` and then unselect `doc_table:highlight`.
