 Hello,

 A Brazilian user is reporting that the following interpolator works only
 for the highest numbers but not for the initial range (555-1855):
 http://www.openstreetmap.org/browse/way/217367683

 I've checked all tags and they all seem correct: all nodes in the
 interpolator have exactly the same value in the "addr:street" tag, all
 numbers are odd (matching the way's "addr:interpolation" tag), and all
 numbers are placed in an increasing sequence.

 I also believe that Nominatim's sanity checks are unlikely to cause this
 since there is about 1 house number for every 1 meter of length throughout
 the whole interpolator, which seems quite acceptable.

 The user has also reported that initially no numbers yielded results. Then
 he split the interpolator into segments (one per range) and this made all
 ranges yield results, but combining the ranges back brought this problem
 back partially. We decided not to split it again so that you can verify
 the issue and perhaps tell us if we're doing anything wrong.
