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.
Now that mutli-word partials no longer exist, multi-word full
words need to be used to search in addresses and therefore no
longer should have a penalty.
Also changes the condition when a full word is included into
the address. It is no longer relevant if an equivalent partial
exists but only if the term consists of more than one word.
When searching for house numbers in the name (for place-only
terms) then the same penalties need to apply as for the
regular house number search.
Change the code to first compute the penalties and then create
the new search variants.
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.
When name and address is empty, the keywords field in the response
of the details API would be an array because that is what PHP's
json_encode defaults to with empty array(). This default can only
be changed globally per json_encode call and that might cause
unintended colleteral damage. Work around the issue by making
name and address an empty array instead of keywords.
Fixes#2329.
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.
These tables have never been actively maintained and the code is
completely untested. With the upcomming changes, it is unlikely
that the code remains usable.
This removes the aux tables and all code that references them.
Disabling query reversal is no longer possible in the configuration,
so there is no need to keep this as an option. Reversal is
automatically disabled for structured search only.
Usually we don't narrow down search results by house number when
only a street name is given because there may be a lot of rows
to cross check when the street name is very frequent. However,
when it is known to be rare, the housenumber check may be done
anyway.
Fixes#2238.
Always look up the closest housenumber before looking up
interpolations. This ensures that closer housenumbers are
preferred over interpolations.
Fixes#2214.
Adds a general higher penalty for special search term and an
additional one if the term is anywhere but the beginning or the
end. Also housenumbers and special searches together are less
likely.
