If your query is taking a long time to complete, try using the {ref}/esql-commands.html#esql-keep[`KEEP`] command and specifying the fields you want returned. For example, add the clause `KEEP @timestamp, user.name` to the end of your query to specify that you only want the `@timestamp` and `user.name` fields returned. NOTE: An error message displays when the query bar is empty.
