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 :
https://gerrit.wikimedia.org/r/plugins/gitiles/search/extra/
<https://gerrit.wikimedia.org/r/plugins/gitiles/search/extra/>
Then I had an error when trying to search something, something like "unknown
highlighter of type [experimental"] which was resolved by :
https://gerrit.wikimedia.org/r/plugins/gitiles/search/highlighter/
<https://gerrit.wikimedia.org/r/plugins/gitiles/search/highlighter/>
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.
2/ My autocompletion is still broken, suggesting only on "Item:QID".
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.
Thanks for your time,
Kevin

It looks like an index error, so I tried to rerun updateSearchIndexConfig.php maintenance
script, but this one gives me the same kind of error too.
`
/mediawiki/extensions/Elastica/vendor/ruflin/elastica/lib/Elastica/Bulk.php: Error in one
or more bulk request actions:
index: /mw_cirrus_metastore_first/mw_cirrus_metastore/namespace-mediawiki--2 caused
blocked by: [FORBIDDEN/12/index read-only / allow delete (api)];
`
I'm a bit confused as I've managed to run this once when I first installed
CirrusSearch, so I don't really understand why it wouldn't work now.
This error may appear when elasticsearch is running low on disk space, it can switch
affected indices to read-only, please see
https://www.elastic.co/guide/en/elasticsearch/reference/6.7/disk-allocator.…
<https://www.elastic.co/guide/en/elasticsearch/reference/6.7/disk-allocator.html>
and the index.blocks.read_only_allow_delete property to reset the read-only flag.
In short: double check disk usage on the partition where Elasticsearch has its data
directory, reset the read-only flag for all indices marked as read-only and rerun the
maint scripts as described in the CirrusSearch README file.
Finally, autocompletion seems to be working even though the search itself doesn't,
but it only autocompletes Item:QID instead of working on the item label, do you have any
idea why ?
The reason you still see results for QID queries is that WikibaseCirrusSearch still
performs a query on the mysql database when it detects QIDs in the search query it's
why you may see search results even though the elasticsearch infrastructure is broken.
