Both answers were taken as typed. A value outside the published shape, such
as hours that are no text, reached the hours parser and failed the details
request. A place outside the shape is now left out of /v1/community, and an
element outside it sends the lookup to Overpass.
Community opening hours laid over OSM details now go through the same parser
as OSM's own, so they arrive as one line per day with open-now and the periods,
and a community description lands in the details' summary. A place copied from
a collection no longer records its values as an import: without an origin row a
value is never sent anyway, and a later edit marks only the fields it changes.
Opening an OSM place asked the public Overpass servers for its tags, which
took five seconds and more and answered nothing while they were down. Where
the TREK services are in use, the details now come from the Places API's
details layer (/v1/osm), with the community values in the same answer, and
Overpass is asked only for an element the layer does not hold.
- The lead is Photon's own row first; a row of its name inside the lead
only stands in where Photon's row went as the same place. Rows without a
line below the name are never folded as reading the same.
- A miss of Photon where it is the geocoder no longer asks it a second time
on the way to an empty answer.
- The transport words of the identity match use a Unicode word boundary
(straße, estación) and match 駅 anywhere.
- Opening an OSM place reads the coordinate it was placed at explicitly.
- The ferry spans of a Valhalla leg move to valhallaFerries.ts, and a day
cut into pieces is asked with one options object.
- "Limit" on the allowance tiles is "Daily limit", which no locale left
as an English copy.
- Tests follow the new behaviour: no Nominatim behind Photon, zoom 13,
and the expectations of the merge and edit-distance cases.
The suggestions and the full search now share one merge. Photon's hits are
ranked with places that have a Wikidata link before their unlinked
namesakes, and its context bias is narrower (zoom 13). The list opens on a
lead where Photon's answer has one: a country or region always; a town,
island or sight when it is called what was typed (or a near typo of it),
lies within 1000 km of where the traveller is looking and no place of that
name ranks above it. Rows of the lead's name inside it, the same element
under two ids and rows that read the same are shown once. A three-letter
code in capitals is asked for as the airport of the bundled list.
Where Photon is the geocoder it answers alone: an empty answer and a miss
are the answer for search and imports, the reverse lookup asks again
within 50 km, a Google place is matched inside a box through Photon, and
an opened OpenStreetMap place is placed by Overpass and named by Photon.
Nominatim stays the search of installations without the TREK services or
with an operator's own Nominatim.
Measured on 5000 places from Wikidata: the right place first while typing
48 % before, 65 % now; full search 53 % to 68 %; no repeated rows.
The suggestion list asked only the TREK index and its OpenStreetMap layer,
because Nominatim's usage policy rules out autocomplete. The layer is a slice
of OpenStreetMap, so many places showed up only once the full search was sent
(#2877). Photon is built for this keystroke: the suggestions now ask it in
parallel with the index and interleave its rows, dropping any the list
already holds, by OSM id or by the search list's same-place rule.
Without Photon (services off, an operator's own Nominatim, a paused or failed
answer) the list reads exactly as before. A failing index no longer throws
away what Photon found, and the Google-only switch skips Photon as it skips
the index.
Refs #2877
An empty Photon search, or one without a hit that has an OpenStreetMap id, is asked again at Nominatim as the reverse lookup already was. The background lane goes to Nominatim alone, a reverse lookup leaves Nominatim half of the caller's deadline, and a 429 with Retry-After pauses Photon for that long.
An installation that holds a key for the TREK services and has no
NOMINATIM_URL of its own now sends the OpenStreetMap search and the
reverse lookups to photon.liketrek.com first. The answers are read into
Nominatim's shape, so the place records stay the same, and every miss
(refused key, allowance spent, timeout, error, foreign body) falls back
to Nominatim, with a one minute pause after four misses in a row.
TREK_PHOTON_URL points at another copy, and the default of
TREK_SERVICES_HOSTS now lists photon.liketrek.com and
valhalla.liketrek.com beside places.liketrek.com.
