We're interested in investigating this, but we need much more detail from you, for example an input string that gives bad results; what results you expected; and the output of about:omnibox in this case with "show all details" and "show results per provider" checked.  (Just copy and paste the text, don't worry about the formatting.)

This has been affecting everyone at my company, so presumably everyone else in the world is affected as well. I attached three arbitrary examples, I used to have many more but have been slowly re-training Chrome by manually re-typing the sites it used to take me to automatically.

The first is "re", which recommended a site I've visited maybe twice this year instead of "reddit.com" which I visit tens of times per day.

The second is "en" which recommended a Facebook branding site I visited a few months ago, instead of "engadget.com" which I visit once every few days.

The third is me trying to force it to recognize "engadget", but Chrome 61 straight-up refuses to do so. It pulls up two results from my browser history near the middle of the list.

Previously typing "y" would recommend some random YouTube video I saw a few weeks ago instead of "youtube.com", "a" would take to a random sub-page on my company's website rather than the page I visit hundreds of times per day, etc.

I suspect the algorithm started weighting results typed in manually much higher than results it correctly picked for you. The results it now refuses to show are things it used to select for me automatically, and the top results it gives now are URLs I typed in manually at some point in the past.

This looks awful.

Can you please submit chrome://omnibox output for "re", for "en", for "engad", for "reddit.com", and for "engadget.com".  These will help us figure out what's wrong in your examples.  Check both the "show all details” and "show results per provider” boxes.

Feel free to paste the results in here unformatted; we’ll be able to decipher them.

thanks,

I attached three web archives, this was with the following settings checked, as requested:

√ Show all details
√ Show results per provider, not just merged results

It's certainly suspicious that it recommended /r/rickandmorty and /r/design in my search results for "re", as those are the only two subreddits I remember *typing in manually* at some point in the past few months. Chrome used to autocomplete the other subreddits, but now it acts like it has no knowledge of me visiting them even though they're in my history.

If it's relevant at all, I and my coworkers all use Macs running the latest Chrome and macOS. Identical to the original poster.

Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/61.0.3163.79 Safari/537.36

The same problem is occurring on Windows.

The omnibox is unusable at this point. Please revert every change that has been made to it since Chrome 60.

Thanks for the about:omnibox data!

Regarding "en" / "engad", Chrome does not appear to think you've ever visited engadget.com by selecting it from the omnibox.  Did you do that recently?  You say that you visit engadget.com every few days.  How do you normally do so?  A bookmark?  A search for engadget, then clicking on the result?  etc?

Regarding "re" / "reddit", Chrome seems to think you've visited resque.calltrackingmetrics.com four times (all using the omnibox) and some reddit pages such as reddit.com/r/rickandmorty twice each (all using the omnibox each time).  Reddit.com, if has been visited, has only been visited according to the output you've provided, at most two times.  How often do you visit the root page, and via what means?

It's hard for me to figure what's happening to you / your coworkers.  All of the omnibox metrics look fine from our end, and we haven't heard any other complaints recently, so this is certainly not a widespread disaster.  Nonetheless, I'd like to get to the bottom of this to determine if the omnibox and the history system or something else is the cause.

To visit reddit I would type "re" and hit enter because it autocompleted to "reddit.com" (using my browser history, not a Google search), would do so tens of times per day. The same goes for Engadget, but maybe once every few days.

**Interestingly both cases now work correctly**, although I don't recall visiting Engadget at all since I last commented. I actually can't find any examples that don't work correctly anymore, despite my efforts to avoid messing with the autocomplete data by using my phone or a different laptop.

Hmmmm.  If things now work correctly, have you restarted Chrome since the last time you saw the bug?  There's a known (but not understood) issue where sometimes the history data seems to not be loaded correctly on the first launch after an upgrade, and the fix is basically to completely shut down Chrome and re-launch.  I wonder if you could be hitting this.  If so, that would be interesting, as we've mostly seen this internally at Google.

That would be interesting, but it seems unlikely. I restarted Chrome many times shortly after upgrading to Chrome 61 after noticing the issue, without success, and I'm pretty sure I haven't restarted Chrome since then. I *did* sign in to Chrome on a different laptop on September 9th.

Checking the local history on each laptop, both of them say I visited engadget.com on September 9th at exactly 11:45:58 GMT-0400 (EDT) (I genuinely don't remember doing this), then before that the first laptop says I visited the site once every two weeks – subpages on the site were visited every 3-5 days, which is weird since I get to these pages by visiting the main engadget.com page. The other laptop wasn't used since February so there's no browser history since then.

I think signing in to Chrome on the other laptop accidentally triggered a sync that fixed things? Other than that it looks like **my browser history is simply wrong somehow**, not tracking my visits to the main domains (possibly when it autocompleted rather than typed manually?) but tracking visits to the subpages.

Glad to hear it isn't a widespread issue.
