 - Fields defined by parse cannot be parsed again. For example, `source=accounts | parse address '\d+ (?<street>.+)' | parse street '\w+ (?<road>\w+)' ;` will fail to return any expressions.
 - Fields defined by parse cannot be overridden with other commands. For example, when entering `source=accounts | parse address '\d+ (?<street>.+)' | eval street='1' | where street='1' ;` `where` will not match any documents since `street` cannot be overridden.
