Hello,
This error was indeed a disk space problem, following your advice I did reset the read-only flag.
I came across multiple errors during the different maintenance scripts that I somehow resolved with a bit of googling, by installing those elasticsearch plugins :
Then I had an error when trying to search something, something like "unknown highlighter of type [experimental"] which was resolved by :
Yes indeed these plugins are needed by CirrusSearch when Wikibase integration is enabled, we definitely need to improve the documentation.
1/ So at this point, the search is working, but I still have a warning upon requesting something : "A warning has occurred while searching: Mixing entity and article namespaces in search is currently not supported. Only entity namespaces will be searched." It appears there is nothing in the log file for this warning.
You are running an old version of WikibaseCirrusSearch. We no longer display this warning message.
The classic page model and wikibase model are completely different and this is a real challenge to provide a seamless and integrated search experience for both types of data. The consensus was to provide an "optimized" query for the wikibase model only if the namespaces requested do include Items types.
Example:
- searching on a Item and Property namespace: wikibase optimized
- searching on Help and Item: warning displayed (your version), wikidata production version: fallback to the classic wiki model
- searching on the default namespaces: it's dependent on your wiki configuration, if you don't setup the list of searched namespaces according to this limitation you will see this warning message for default searches
In other words: wgNamespacesToBeSearchedDefault[1] needs to be configured in a way that does not mix Item/Property namespaces with Wikipage namespaces.
2/ My autocompletion is still broken, suggesting only on "Item:QID".
Are you using the wbsearchentities API (which should be enabled when searching top right for ltr languages)?
The completion results displayed when using the Special:Search search box might not use this API leading to QIDs being displayed.
3/ I noticed something odd with search results. I was trying to search an entity which has multiple aliases in different language (atleast 3 or 4), by typing one of its french aliases :
- When my UI is in English, the entity is found but the highlight and the alias shown is from another language, neither french or english. - When my UI is in French, it shows me the correct french highlight and alias or label.
I don't know if I'm clear, in both cases the entity is found correctly, but its highlighted label or alias is not consistent across the different UI languages.
No it's not, it is language dependent, every language has a list of fallback and french is not a fallback for english, but english is a fallback for french. When searching in english there are no guarantees that the ranking nor the data displayed will be the same. This was done to address the ambiguities between languages, e.g. when searching for "or" in french you would like to see Gold but if you were english you would perhaps expect something else.
