Comment (by franjavitino@…):

 Another test case:

 If i request this with the postalcode:
 http://nominatim.openstreetmap.org/search?format=json&limit=5&street=C%2F%20Progres%2C%2069&city=Gav%C3%A0&postalcode=08850&country=Espa%C3%B1a

 It returns two locations, apparently ignoring the postalCode:
 -Carrer del Progrès, Torre Gavá, Gavà, Bajo Llobregat, Barcelona,
 Cataluña, 08840, España (41.2995446, 2.0122305)
 -Carrer del Progrès, Torre Gavá, Gavà, Bajo Llobregat, Barcelona,
 Cataluña, 08850, España (41.2975538, 2.0088409)

 If i request the url without the postalcode, returns 3 matches:
 -Carrer de Progrés, Torre Gavá, Gavà, Bajo Llobregat, Barcelona, Cataluña,
 08840, España (41.3016208, 2.0139323)
 -Carrer del Progrès, Torre Gavá, Gavà, Bajo Llobregat, Barcelona,
 Cataluña, 08840, España (41.2995446, 2.0122305)
 -Carrer del Progrès, Torre Gavá, Gavà, Bajo Llobregat, Barcelona,
 Cataluña, 08850, España (41.2975538, 2.0088409)

 There are two 08840 and one 08850, so I assume there is some bug on the
 search (or it displays it for some reason).
