Q:

DuckDuckGo: Exact string search within a domain

I searched DuckDuckGo for site:wikipedia.org "advisary", hoping to spot some typos.
To my surprise, DuckDuckGo replied with articles that do not contain the word "advisary", even thought I took the pain to put it inside quotes.
I notice that this behavior only occurs in conjunction with the usage of the site: keyword.
How to search for an exact string within a domain with DuckDuckGo?

A:

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!)
