As requested, "an API for that across-all-wikis fulltext search yet? Maybe just on Toolforge?"

Description
Provide an API that would allow users to perform a full text search across all Wikimedia wikis. Due to the cost, perhaps extremely rate limited to limited to requests for access.
When asked about the suggestion, the a search engineers said the following:
"we asked for a budget to do it on toolforge. It wasn't approved.
well, it was approved in the sense of "we wont give you money for it, but if theres any left over then maybe"
in theory we could setup a rediculously rate limited api for it without much work against the prod clusters.
(and also limiting keywords agressively, like no regex)"
