Introduce a flag to always search the entire history from the omnibox

Description

Never exclude history from the omnibox, always suggest all history. Keep the ranking, but never exclude anything

Who's implementing?

• I'm willing to implement this feature myself

The problem

Sometimes, when I type something into the omnibox, history doesn't show up. I'm using the flag to keep history indefinitely, so it's not that. If I enter the URL manually into the omnibox, it will recognize that it's in my history.

Observe:

It does not suggest from my history.

It knows this link is in my history.

It does not display the title or icon for links that are not in my history.

Only after I have visited the site does it start suggesting the site again.

Possible solutions

The omnibox ranks history suggestions, which is fine, but I should be able to tell it never to fully exclude anything. It has the potential to be extremely powerful if I can use it to search my entire history, but it seems it only works for history I have visited very recently. This is mildly infuriating.
