We've previously added searching through rank 30 in a house
number search to enable searches for house number+name.
This had the unintended side effect that rank 30 objects
are also returned in s search that dropped the house number
from the query. This is wrong because POIs cannot function
as a parent to a house number.
This fix drops all rank 30 objects from the results for a
house number search if they do not match the requested house
number.
- only save partial words without internal spaces
- consider comma and semicolon a separator of full words
- consider parts before an opening bracket a full word
(but not the part after the bracket)
Fixes#244.
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.
The tokenizer to be used can be choosen with -DTOKENIZER.
Adapt all tests, so that they work with legacy_icu tokenizer.
Move lookup in word table to a function in the tokenizer.
Special phrases are temporarily imported from the wiki until
we have an implementation that can import from file. TIGER
tests do not work yet.
This adds an installation step for PHP code for the tokenizer. The
PHP code is split in two parts. The updateable code is found in
lib-php. The tokenizer installs an additional script in the
project directory which then includes the code from lib-php and
defines all settings that are static to the database. The website
code then always includes the PHP from the project directory.
Indexing is now split into three parts: first a preparation step
that collects the necessary information from the database and
returns it to Python. In a second step the data is transformed
within Python as necessary and then returned to the database
through the usual UPDATE which now not only sets the indexed_status
but also other fields. The third step comprises the address
computation which is still done inside the update trigger in
the database.
The second processing step doesn't do anything useful yet.
Drops all calls to PHP utility functions. nominatim cli functions
are used where possible, to stay as close to the final code as
possible with the tests.
By removing the PHP calls, the test code now only uses osm2pgsql and
the database module from the build directory.
Always look up the closest housenumber before looking up
interpolations. This ensures that closer housenumbers are
preferred over interpolations.
Fixes#2214.
So far the data directory constant has pointed to the source
directory to be usable with different subdirectories. Now only
the data subdirectory itself is being used with the constant,
so point to the directory directly.
This replaces {data_dir}/settings throughout the code, so that
the configuration may be placed somewhere else in the directory
structure (e.g. in /etc).
The PHP scripts need to know the position of the nominatim
tool in order to call it. This is handed in as environment
variable, so it can be set by the Python script.
In the future, the BDD tests will simply set up the required
test database themselves. Like with the template database, it
is not reimported when it already exists unless that is explicitly
forced.
Makes most of the API tests currently fail because they still
point to old test data.
Introduces a new class DBRow that encapsulates the comparison
functions. This also is responsible for formatting more informative
assert messages. place and placex steps are unified.
Put the connection to the test database into auto-commit mode
and get rid of the explicit commits. Also use cursors always in
context managers and unify the two implementations that copy
data from the place table.
The project directory contains the website script as
configured through the test configuration. This means
that tests are now completely independet of any
configuration that may be contained in the build
directory.
Also removes the hack to inject additional settings via
a environment variable.
DB tests now can simply set the environment to change configuration
variables. API tests still rely on a configuration file.
Also, query.php needs to set up the CONST_* variables to work with
the query scripts. That is a tiny bit messy and duplicates code
but this part will need to be reworked later.
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.
Update names in the coutry_names table on the fly from incomming
OSM country data. Adding a small sanity check that the country
must be an OSM relation and within the area where we expect the
country to be.
If a place node is already linked against a boundary, it should not
be used for linking again. It is usually a sign of a mapping error,
when there are multiple boundary candidates. This change just avoids
inconsistent data in the database, it does not guarantee that the
linking is against the more correct boundary.
Rank 30 objects usually use the address parts of their parent.
When the parent has address parts that are areas but not marked
as isaddress, then the parent might go through multiple administrative
areas. In that case recheck if the right area has been choosen
for the object in question instead of relying on isaddress.
Note that we really only have to do the recomputation in the
case of 'isarea = True and isaddress = False' which hopefully
keeps the number of additional geometric operations we have to do
to a minimum.
There is one more special case to be taken into account here: a
street may go through two administrative areas and a house along
that street is placed in one of the area while the addr:* tags
says it belongs to the other. In that case we must not switch
the isaddress to the one it is situated. To avoid that recheck
the address names against the name of the ara. That is not perfect
but should cover most cases.
Fixes#328.
House numbers need special handling because they may appear after
the street term. That means we canot just use them as the main name
for searches where the address has its own search term entries.
Doing this right now, we are able to find '40, Main St, Town' but not
'Main St 40, Town'.
This switches to using the housenumber token as the name term instead.
House number tokens can get special handling when building the search
query that covers the case where they come after the street.
The main disadvantage is that this once more increases the numbers
of possible search interpretation of which we have already too many.
no penalty for housenumber searches
The previous behaviour was a left-over from a former version
where such POIs parented to the street. Now that they parent to
places, it should be included.
get_addressdata() now also checks if the place itself has entries
in the place_addressline table and merges them into the results.
Also restrict checking for address tag places to cases where the
name cannot be found in the parent's address search terms. Looking
up all address tags is just too slow.
While previously the content of addr:* tags was only added
to the list of address search keywords, we now really look up
the matching place. This has the advantage that we pull in all
potential translations from the place, just like all the other
address terms that are looked up by neighbourhood search.
If no place can be found for a given name, the content of the
addr:* tag is still added to the search keywords as before.
Go back to using centroid when determining if one admin level
is within another. There are cases where boundaries are slightly
misaligned due to mapping errors (not using the same ways in the
relations).
Only declare boundaries the same when they have the same wikidata
tag _and_ have exactly the same geometry. This works around tagging
errors with the wikidata tag, which happen because of automated
edits to the wikidata tag.
The Polish community maps admin boundaries that span multiple
levels by duplicating the boundary relations. Detect this situation
by looking out for matching wikidata tags. The higher ranked
duplicates are then thrown out from the address pool by setting
their address rank to 0.
When a POI has no addr:street but an addr:place that is not
contained in the name list of the parent place, then remember
this situation and merge the content of addr:place into the
address output.
We don't need to care about translations in this case because
it is obvious that no object with translations exists if the
parent isn't the object named in addr:place.
If an addr:place is given but no addr:street tag, then bind
the rank 30 object always to a <=25 object, even when there
is none found with the same name.
When a place of rank 30 has addr tags that are not covered by the
search terms of the parent, add a separate entry for the POI in
the search_name table that includes the addr tags. We can only
do that with named places. For POIs without a name the housenumber
is used as name. If that is not available either, searching still
won't work.
place=postcode places are artificial places that collect addr:postcode
points for aggration. They should neither show up in the address nor
be searchable. That means that there is no need to index them at all.
Only let boundary=postal_code through which define correct areas for
postcodes.
Boundaries shound derive the address part type from the
linked place if possible. This was already implemented
for the address objects but not for the address information
from the address itself.
Fixes#1949.
It may happen that two different postcodes normalize to exactly
the same token. In that case we still need two different entries
in the word table. Token lookup will then make sure that the correct
one is choosen.
Fixes#1953.
