This help page explains the situation best:
Our intention is to not auto-correct searches. That is, we intend to completely respect the query you type in, and (in some cases) display a 'Did you mean?' link at the top when relevant.
However, there are a few outstanding major bugs in this area that we are working to resolve. As a result, you may see some auto-correct behavior in the search results.
Unfortunately, these bugs involve a bunch of APIs that are mostly out of our control. We are both working around these bugs and also working to get them fixed .
For some queries, it has been a little slow to resolve, but rest assured that this is a top priority. In any case, specific examples always help as we may be able to easily add more workarounds.
(Thanks for the specific example!)

So it might help those in need of specific queries like
