String input "all", followed by quickly changing query breaks search bar

When I enter the string "all" into the search bar on https://api.emberjs.com/ember/release, I see a console error logged:

Unhandled Promise Rejection: TypeError: undefined is not an object (evaluating 'this.get("result.module").includes')

After this error occurs, the search feature becomes unresponsive (so backing out "all" and then entering a new query string shows the old results).

To add to the original post, this doesn't seem to reproduce unless I fairly quickly type something else into the search bar which appears to result in a different console error:

Unhandled Promise Rejection: TypeError: undefined is not an object (evaluating 'this.boundList[0].firstNode')

What are you trying to search for when you type “all”? This may help with narrowing down the issue, if there’s some specific method in the docs that is the problem.

Hey @jenweber, I think that I might have been looking for alias or something like that, but it has been a few days so I don't totally remember.

I stepped through the error a bit and I think that first one is happening because the entry associated with "node_modules/rsvp/lib/rsvp/promise/all.js" does not have a top level module property:

...
  {
      "file": "node_modules/rsvp/lib/rsvp/promise/all.js",
      "line": 3,
      "class": "Promise",
      "name": "all",
      "static": 1,
      "_tags": ["module:undefined", "version:4.8.0"],
      "hierarchy": { "lvl1": "Promise", "lvl2": "all" },
      "objectID": "969593002",
      "_highlightResult": {
        "name": {
          "value": "<em>all</em>",
          "matchLevel": "full",
          "fullyHighlighted": true,
          "matchedWords": ["all"]
        },
        "hierarchy": {
          "lvl1": {
            "value": "Promise",
            "matchLevel": "none",
            "matchedWords": []
          },
          "lvl2": {
            "value": "<em>all</em>",
            "matchLevel": "full",
            "fullyHighlighted": true,
            "matchedWords": ["all"]
          }
        }
      }
 ...

This causes an error on line 16 in app/components/search-input/dropdown-result.js where it tries to unpack that value as: let module = this.get('result.module');.

It looks like we get the same behavior any time that we search for all, race, reject, or resolve and that the entries breaking it are the ones scoped to the Promise class from the RSVP project.

We probably need to update the docs in some way so that these entries end up getting scoped to the right module rather than being undefined.

Alternatively/Additionally, maybe we could update this DropdownResult component to drop those results which don't have the expected structure?

Do you have any thoughts, @jenweber?

This continues to happen after the redesign branch merged.
