[Geocoding] Local Nominatim instance incorrectly geocoding locations in Escondido, CA USA

[John Shimer]

Hi,

About 3 months ago I set up a local instance of Nominatim 2.3.1 with a 
scope of North America. In general things are going quite well, but I 
have recently run into an issue that I can't seem to resolve.

All geocoding and reverse geocoding queries involving locations within 
Escondido, CA, will not return Escondido, CA in the address. Nearby 
hamlets like Ponderosa Club Mobile Home Park, are returned instead. For 
example...

the query - 545 West Washington Avenue, Escondido, CA  (33.124267, 
-117.091156)
returns - 545, West Washington Avenue, Ponderosa Club Mobile Home Park, 
San Diego County, California, 92025, United States of America.

If I go out to the Openstreetmap Nominatim instance, the correct result 
with a city name of Escondido is returned. I noticed that the geometry 
of the Escondido city relation in the OSM data base is rather complex, 
but it looks correct to me.

I've already tried reimporting/reindexing the city relation, but that 
does not seem to help.

Any assistance resolving this issue would be greatly appreciated.

Thanks,
John Shimer
