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.
The parameter got lost when switching to website settings.
Given that the use of a fixed parameter is limited,
debugging output can now only be set via the URL parameter.
So far we've used a buffer around a place node to define its
potential address reach. This had two problems: the buffer was
so large that addresses often contain false positives and the
buffer is really distorted when getting closer to the poles.
Change the buffer here to draw a bounndig box at a certain
distance in meter. This means that we always use the same
box everywhere on the planet and can make the extent much
smaller. Using a box has the advantage that it is much faster
to figure out if a point is within the box.
A lot of streams in OSM are of minor importance, they certainly
should show up lower in the list of results than villages. Those
rivers/streams that are well known have a wikipedia page and get
a higher importance from that.
The disadvantage with downgrading is that the address gets even
more useless but that's something that needs to be solved outside
the rank search.
Gets rid of the hard-coded expection for place nodes and sets
the address rank generally via the address level config instead.
That means only administrative boundaries are now used at that
level in addresses.
Remove unnamed landuses and postcode points from
importing. The latter will cause all objects with
address tags to be imported after all. Not expected
in the admin import style.
Instead add it as a configurable path with the one from
the source directory as the default.
Also reinstates that settings/defaults.php is installed as
settings/settings.php.
The initial search and address rank is saved in a table
that is set up from a json configuration file. Ranks may
be assigned on a country level according to class and
type of the object. Special handling that depends on the
geometry or OSM type is still hard-coded in placex insert.
The new default config file mimicks the current assignment
as close as possible. A couple of exceptions have been
removed, most notably the exception for Irish townlands.
Don't do anything if a downloaded diff is empty after all
(may be happening when an empty diff was published upstream).
Correctly compute the waiting interval before checking for new
data. As the interval is now computed based on the date of the
newest object in the database, the configured intervals need
to be adjusted slightly to take into account the time it takes
for the server to publish a diff.
Compare the normalized terms imported with the special
terms script with the normalized version of the query string.
Disregard them if they cannot be found. This avoids a significant
number of mismatches due to transliteration issues.
The match will only be done when a normalized word has been set
making this change backwards compatible with older databases.
Pyosmium comes with convenient functions for finding the
right state and does not require external files for
rembering the state. Updates can now conveniently
set up by simply running ./utils/update.php --init-updates
and state is kept directly in the import_status table.
This change requires an update in the database schema.
Run the following to update:
ALTER TABLE import_status ADD COLUMN sequence_id integer;
ALTER TABLE import_status ADD COLUMN indexed boolean;
ALTER TABLE import_osmosis_log ADD COLUMN batchseq integer;
Search results can become odd without the country search
terms, so make their inclusion a mandatory part of the
setup.
Also adds a new configuration variable to restrict the
languages taken into account by Nominatim.
Utils scripts must be run from the build directory to make sure
we get the right paths. Rename the settings file in source and
replace the original one with an error, so that scripts
fail with an understandable error message when run from the
source directory.
