 <div class="paragraph"><p>Parse the query string and match specific values against

 constraints.</p></div>

-<div class="paragraph"><p>This function allows easily retrieving expected values

-from the query string, validating and converting them

-in one call. In addition, the keys are converted to

-atoms, making manipulation that much simpler.</p></div>

+<div class="paragraph"><p>Cowboy will only return the query string values specified

+in the fields list, and ignore all others. Fields can be

+either the key requested; the key along with a list of

+constraints; or the key, a list of constraints and a

+default value in case the key is missing.</p></div>

+<div class="paragraph"><p>This function will crash if the key is missing and no

+default value is provided. This function will also crash

+if a constraint fails.</p></div>

+<div class="paragraph"><p>The key must be provided as an atom. The key of the

+returned map will be that atom. The value may be converted

+through the use of constraints, making this function able

+to extract, validate and convert values all in one step.</p></div>
