var cities=city.find('metouia');
console.log(cities[0]);
/*
{ country: 'tn',
name: 'metouia',
nameAccent: 'M�touia',
region: '29',
population: '',
lat: '33.959175',
long: '9.99619' }

var cities=city.find('metouia',function(results){
if(results && results.length){
console.log(results[0]);
}

/*
{ country: 'tn',
name: 'metouia',
nameAccent: 'M�touia',
region: '29',
population: '',
lat: '33.959175',
