Point-in-polygon queries are much faster with a SP-GIST geometry
index, so use that for the index used to check if a housenumber
is inside a building.
Only available with Postgis 3. There is an automatic fallback to
GIST for Postgis 2.
Adds a tagger for names by language so that the analyzer of that
language is used. Thus variants are now only applied to names
in the specific language and only tag name tags, no longer to
reference-like tags.
Implements per-name choice of analyzer. If a non-default
analyzer is choosen, then the 'word' identifier is extended
with the name of the ana;yzer, so that we still have unique
items.
Adds a second callback for the analyzer which is responsible
for parsing the configuration rules and converting it to
whatever format necessary. This way, each analyzer implementation
can define its own configuration rules.
Adds a mandatory section 'analyzer' to the token-analysis entries
which define, which analyser to use. Currently there is exactly
one, generic, which implements the former ICUNameProcessor.
Adds parsing of multiple variant lists from the configuration.
Every entry except one must have a unique 'id' paramter to
distinguish the entries. The entry without id is considered
the default. Currently only the list without an id is used
for analysis.
Sanatizer functions allow to transform name and address tags before
they are handed to the tokenizer. Theses transformations are visible
only for the tokenizer and thus only have an influence on the
search terms and address match terms for a place.
Currently two sanitizers are implemented which are responsible for
splitting names with multiple values and removing bracket additions.
Both was previously hard-coded in the tokenizer.
There is no need for the additional layer of indirection that
the ICUNameProcessorRules class adds. The ICURuleLoader can
fill the database properties directly.
Adds class, type, country and rank to the exported information
and removes the rather odd hack for countries. Whether a place
represents a country boundary can now be computed by the tokenizer.
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.
When matching address parts from addr:* tags against place names,
the address names where so far converted to full names and compared
those to the place names. This can become problematic with the new
ICU tokenizer once we introduce creation of different variants
depending on the place name context. It wouldn't be clear which
variant to produce to get a match, so we would have to create all of
them. To work around this issue, switch to using the partial terms
for matching. This introduces a larger fuzziness between matches but
that shouldn't be a problem because matching is always geographically
restricted.
The search terms created for address parts have a different problem:
they are already created before we even know if they are going to be
used. This can lead to spurious entries in the word table, which slows
down searching. This problem can also be circumvented by using only
partial terms for the search terms. In terms of searching that means
that the address terms would not get the full-word boost, but given
that the case where an address part does not exist as an OSM object
should be the exception, this is likely acceptable.
Instead of requesting the match tokens from the tokenizer
when looking for parent streets/places and address parts,
hand in the saved tokens and ask if they match. This gives
the tokenizer more freedom to decide how name matching
should be done.
