Search does not list Class all properties nor methods

When I'm trying to find a method on a Class of the API, let's say `route` => `model`. This does not appear in the search result list of the search dropdown. Further example: `controller` => `queryParams` property


## Expected
The search results lists all class properties and methods.

## Actual Behavior
The search results are empty or do not include the specific property / method.

I would like to help to fix this bug, but first, I wanted to see if this isn't actually intended behavior? Maybe the YUIDoc conventions are not met? Any hints? :thinking:
