Hi,

While evaluating the results of the findNearbyPostalCodes webservice for locations in The Netherlands, I ran into the following issue:

I used the following queries:

http://ws.geonames.org/findNearbyPostalCodes?lat=51.55&lng=5.09&style=LONG
http://ws.geonames.org/findNearbyPostalCodes?lat=51.55&lng=5.09&style=LONG&maxRows=1

The result of the first query (without maxRows=1):

<geonames>
<code>
<postalcode>5009</postalcode>
<name>Tilburg</name>
<countryCode>NL</countryCode>
<lat>51.55</lat>
<lng>5.1166667</lng>
<adminCode1>NB</adminCode1>
<adminName1>Noord Brabant</adminName1>
<adminCode2/>
<adminName2>MIDDEN-NOORD-BRABANT</adminName2>
<distance>1.843766967748772</distance>
</code>
<code>

<code>

<adminCode2/>
<adminName2>MIDDEN-NOORD-BRABANT</adminName2>
<distance>2.235705232137345</distance>
</code>
</geonames>

The results of the second query (with maxRows=1):

<geonames>
<code>
<postalcode>5056</postalcode>
<name>Berkel-Enschot</name>
<countryCode>NL</countryCode>
<lat>51.53000002</lat>
<lng>5.0866667</lng>
<adminCode1>NB</adminCode1>
<adminName1>Noord Brabant</adminName1>
<adminCode2/>
<adminName2>MIDDEN-NOORD-BRABANT</adminName2>
<distance>2.235705232137345</distance>
</code>
</geonames>

In my opinion, the second query should return the closest result, but as you see it doesn’t. Doesn’t that sort ascending on distance?

Thanks Marco. This is was a bug and was fixed right now.
