There are some pathological cases where an isolated letter may
be deleted because it is in itself meaningless. If this happens in
the middle of a sentence, then the transliteration contains two
consecutive spaces. Add a final rule to fix this.
See #2909.
Removes territories of US, France, Australia and Netherlands from the
country list. These territories have their own country code (which is
why they are in the list in the first place) but are mapped as part of
the admin_level 2 relations for the respective parent countries.
Therefore they never had any places attached. In practical terms, the
change only affects the number of tables created.
Canada has complete coverage for administrative boundaries on
county level. Removing the county nodes from the addresses avoids error
due to a wide-spread doubling of place nodes for city counties.
The Letter class does not include non-spacing marks that can also
have a consonant or vowel meaning, especially in Indian languages.
Use the alnum propoerty instead which includes them all. Also
include the vowel-canceling Virama, which is not a letter by itself
but changes the transliteration.
The OSM data has been sufficiently cleaned up by now that
the operator no longer needs to be considered a name tag.
Use 'brand' as the searchable alternative.
Given that the tag is most of the time duplicated by an amenity
tag which is already imported, only import it as a fallback when
there is no name.
Fixes#2609.
Mutations are regular-expression-based replacements that are applied
after variants have been computed. They are meant to be used for
variations on character level.
Add spelling variations for German umlauts.
While technically being a letter, the apostrophe is often replaced
with a normal apostrophe in writing which is a punctuation mark.
This makes sure that the modifier letter apostrophe yields the same
normalization results and thus is really interchangable.
Only has an effect after the next reimport.
Fixes#2569.
The highway key is being used more and more for non-ways these
days. This clashes with Nominatim's assumption that essentially
everything that has a highway tag can be used as the street part
of the address.
Change the default rank of highway objects to 30 to avoid this.
Only the known values for streets keep the rank 26 and are now
listed explicitly.
