Query String: fix comparisson when retrieving some variable
Query String: fix comparisson when retrieving some variable

Under similar variables in the query string, the API was returning
the value of the shorter variable name without compare the lenght
string. E.g: if exists two keys 'd' and 'data', it always return
the value of 'd' when quering for 'd' and 'data'.
