Subject: Remove special search for address part for long ways
X-Git-Tag: v3.2.0~34^2
X-Git-Url: https://git.openstreetmap.org./nominatim.git/commitdiff_plain/713ea080d2cf6b5a5e412b63111f81336fa2f7f0

Remove special search for address part for long ways

Ways now always have the complete set of crossing boundaries
independent of the length.

Fixes #1108.
