Levels choosen according to OSM wiki. Mainly moves admin_level 6
to county level and admin_level 8 to city/town level. Higher
levels are adjusted accordingly.
Fixes#2453.
Adjusts levels for boundaries according to the list on
https://wiki.openstreetmap.org/wiki/Tag:boundary%3Dadministrative
* no admin_level 5, so drop that from addresses
* admin_level 6 has the province
* admin_level 7 has the county when it exists
Also reranks place=province so that it matches up with
admin_level 6 and introduces place=civil_parish which
is used as a place node for some admin_level=9 boundaries
in Galicia.
The new icu tokenizer is now no longer compatible with the old
legacy tokenizer in terms of data structures. Therefore there
is also no longer a need to refer to the legacy tokenizer in the
name.
name:etymology contains a description of the name origin and is
thus more informative than search-worthy.
name:signed basically indicates that the feature does not have
a name.
Two replacement words directly following each other did not
work as expected because each expects a space at the
beginning/end while there was only one space available.
Also forbit composing a word after a space was added in the
end by a previous replacement.
Make sure all special symbols are removed during normalization already.
Those won't be interpreted in any way because they are unlikely to be
searched for.
The new format combines compound splitting and abbreviation.
It also allows to restrict rules to additional conditions
(like language or region). This latter ability is not used
yet.
This adds precomputation of abbreviated terms for names and removes
abbreviation of terms in the query. Basic import works but still
needs some thorough testing as well as speed improvements during
import.
New dependency for python library datrie.
The tokenizer configuration has become difficult to handle
due to the additional manual transliteration rules. Allow
to have a separate rule file that is given to the ICU library
as is.
The ICU library only offers transliterations for a limited set of
script. Add transliterations for missing scripts from the PostgreSQL
module. These means that the same selection of scripts is supported
as with the old module.
This adds the boilerplate for selecting configurable tokenizers.
A tokenizer can be chosen at import time and will then install
itself such that it is fixed for the given database import even
when the software itself is updated.
The legacy tokenizer implements Nominatim's traditional algorithms.
- the command is now --import-special-phrases
- the output is not an sql file anymore, data are directly imported to the database.
- the little part on the documentation (section data import) has been modified.
As we can't refer to the project root dir in the module path, the
module path may now also be a relative directory which is then
taken as being relative to the project root path.
Moves the checkModulePresence() function into the Setup class, so
that it can work on the computed absolute module path.
CONST_BasePath is split into separate configuration variables
for binaries, libraries and data. These variables as well as
the installation path are now set in the executable directly and
no longer configurable via project settings.
This is the first step towards an installable software. The
executables should know per installation where to find their
necessary data to execute. Project configuration needs to be
restricted to settings that really concern the specific Nominatim
installation.
There are two places where the website URL is still used:
for icons, replace the URL with a link to the icon repository
of the UI repo. The more URL now builds the link from the
server info.
Rank 25 is now available for places that should appear in addresses
but not when a street is present. Use this for som block-like
place types. Also document the particularity of rank 25.
subdevisions and allotments are now at the same level as landuse
which they are frequently used together with.
Removes admin level 7, which should not exist and promotes
admin level 8 to municipality level.
place=municipality is only used for boroughs of St. Petersburg,
so demote to level 18.
Fixes#926.
These are used to mark large paved areas. Sometimes they exists
together with named regular streets. In such cases the unnamed
area may overshadow the actual street when computing the address
parent. As unnamed highways are not very useful anyway, we
simply remove them from the database.
Postal boundaries usually just have the postcode tag set and are
therefore officially 'nameless'. We want to have them as
boundary=postal_code anyways in order to distiguish them from postcode
points inherited from addr: tags.
Boundaries and places now always get a rank < 26 to make sure that
they do not parent to a street. Skip boundary=place completely
because they will be covered throught the secondary place tag.
Squares are now addressable (on address level 25) and thus can
be attached to a house number via addr:place. Needed to increase
the rank range for matching up addr:place to 25.
Traffic signs rarely have name and are therefore mostly not
searchable. Remove them completely. Allow street lamps only when
they have a name. Removes about 2M object from a planet instance.
