E.g., the query {{Code|Hello, Bob}} will result in a search for the criteria "Hello," and "Bob", independently.
But what if I want to search for something belonging together that contains a space character, e.g. "{{Code|2015-05-27 20:34" }} or "{{Code|Layer IV"}}?
In this case, wrap your connected phrase into quotation marks ({{Code|"}}) - the search text interpreter will handle it as a single criterion.
Example: {{Code|Chuck "He who needs no nickname" Norris}} will result into three criteria (one of them being the phrase "He who needs no nickname").
