Automatically repopulate the tokenizer/ directory with the PHP stub
and the postgresql module, when the directory is missing. This allows
to switch working directories and in particular run the service
from a different maschine then where it was installed.
Users still need to make sure that .env files are set up correctly
or they will shoot themselves in the foot.
See #2515.
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.
Convert the '_place_*' entries back to normal entries before
returning them in the 'namedetails' section. If the name field is
duplicated, kept the '_place_*' notation. This preserves the previous
behaviour before _place_ names were introduces but adds the additional
names from the linked place for reference.
This keeps the names tracable and ensures that all names are searchable
when they differ. Do not keep names when they are exactly the same
to save some space. Linked names are cleaned out before relinking.
An expression of the form 'SELECT (func()).*' will be expanded
by Postgresql _before_ execution with the result that the function
will be called as many times as there are fields in the record.
This is not what we want. The function call needs to go into
the FROM clause instead.
This lays the groundwork for adding variants for housenumbers.
When analysis is enabled, then the 'word' field in the word table
is used as usual, so that variants can be created. There will be
only one analyser allowed which must have the fixed name
'@housenumber'.
When changing something in the default configuration of the sanatizers
that refers to an analyzer that is not yet loaded, there shouldn't be
any errors.
This gives the analyzer more flexibility in choosing the normalized
form. In particular, an analyzer creating different variants can choose
the variant that will be used as the canonical form.
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.
The name query already looks for the existence of housenumbers and
may as well retrive them. Saves up to threee additional lookups.
It also means that we can lift the restriction on looking
for existance of housenumbers for simple queries only.
