which would make the full data
set available for raw queries (directly to elasticsearch) to labs users.
When issuing raw queries you can query every index in elasticsearch. its
not performant at all, but it would work.

Unfortunately there is not a single index that is then
filtered by tags,
in WMF production we currently have 1824 different search indexes. Due to
these being all independent search indexes the scores generated by queries
in one in index are not directly comparable to the scores generated by
querying another index (we can't just naively merge the result set's
together). By having these as separate indexes our busiest index
(enwiki_content) is able to be kept down to only querying against 150GB of
data, rather than querying the full cross-wiki data set which represents
2.5TB of data. This ends up being very important as we serve 1.5-3k queries
per second against this index.

I seem to remember that all Wikimedia wikis now
share a single search
index, and per-wiki searches are filtered through a tag for the
respective
wiki.
If that is indeed the case, is there an API to search all wikis, but
omitting that tag?
