Write the city, town or village with small letters. If not appear, write with English letters, or/and choose the Country at the previous option. You can also write only the first letters of the city and expect to get results to choose from.If you did not choose Country and you use Whole World you can type also the country to minimize the results. For United States only type US and not United States. For example if your city is San Francisco, typesun francisco usIf the city is Washington because there are too many Washington's you can type also the state example:washington us californiaBut if you have choose Country before and you use the United States for example type only the city/town/village and not the country.If you do some tries to find your city and the script seems to not work, for example you can't see the small rolling wheel at the right of the bar where you type, just retype the city or backspace the last letter and retype it.
