Is there something wrong with the exact match operator ("")?

I have been getting result that are not matching phrases exactly. Instead, they are of the nature you would expect from a normal search. For example, have a look at this search https://duckduckgo.com/?q=%22does+girls+hair+grow+faster%22
Notice how on the third result there are words between does and the rest of the phrase, or in the case of searches 4,5 and 6 the phrase is not matched at all. 

Is this normal, or is there a problem? Thanks to anyone who answers!

P.S Sorry for the silly search I was just trying to think of an example haha.

I'm having the same problem. Here is a search I done with something purposefully tricky to show what I mean https://duckduckgo.com/?q=%22is+is+this+right%22, The problem here is some of the searches do not contain to two "is". It would be great if you guys could fix this.

There's been some progress here, though some examples may be cached so you can try changing the casing to get a fresh one: e.g.  https://duckduckgo.com/?q="IS+tHIs+riGht"

The example, "does girls hair grow faster" is still an issue so, that one, we're still looking into :)

We'd appreciate any testing around quoted searches showing non-exact matches in the top 10 results.

Also, we're working on some bugs with bolding so sorry for any cases where the whole phrase isn't bolded but does appear.

I just tried searching "zebra finch bird song" and non of the top results contain the exact phrase:

https://duckduckgo.com/?q=%22zebra+finch+bird+song%22

Thanks for working on this.

Same here, with the search of "valeur PR".
By the way, it would be nice to have a "case sensitive" checkbox.

Yet another using:

  "root= "

Even using "root=" (without the trailing space) does not return anything with "root=" in the results

Punctuation isn't easily indexed by most search engines and it impacts us as well. We also use multiple sources for results which sometimes don't support the same level of syntax search.

Another example: -
"Hits and Memories" collection CD
This search only returns 3 matches in the first 19 results. I just sent a Feedback message before finding this thread.

That can't be a bug, can it?
Searching for phrases is a basic search engine feature, until someone decides that algorithms know better than the user... I really did not expect DDG to go down that path... and I still hope I'm wrong.

It is. We use quite a few third-party sources to get results, and sometimes they decide to break things like this. When that happens, we have to detect queries that won't work with certain sources and either disable those sources or filter their results again afterwards. Lots of crazy bits in there, unfortunately.

Thanks for the answer. Now regarding those sources, ditch them (if possible) ! Users playing with quotation marks are usually willing to lose some recall to preserve precision.
