Searching

How to search?

First you need a Hash with the criteria that you want to search.

# example of criteria
criteria = {
  country_code: 'US',
  name: 'New York',
  featureClass: %w[P S],
  maxRows: 1,
  style: 'short'
}

Then you can search

result = GeoNames::Search.search(criteria)

The result it will be a Hash if was successful, like this one:

{ "totalResultsCount" => 1360,
  "geonames" => [
    { "lng" => "-74.00597",
      "geonameId" => 5128581,
      "countryCode" => "US",
      "name" => "New York",
      "toponymName" => "New York City",
      "lat" => "40.71427",
      "fcl" => "P",
      "fcode" => "PPL"
    }
  ]
}
