Subject: [PATCH 1/3] Fix desc order in paginate.

Order desc was sorting per page, not like real pagination, now it's working with me well.

Subject: [PATCH 2/3] Update TNTSearchEngine.php

That's better, the perv if the paginate 20 and last page has 4 results won't get them.

Subject: [PATCH 3/3] Faced problem in laravel 8 while order pagination

There is changes i don't understand it, but it works to me like in charm, get all IDs then order them in paginate, no more "rsort" or something else.
But i don't understand "keyBy($model->getKeyName())", if my pagination IDs is:
10
9
3
By "keyBy($model->getKeyName());" turns to:
3
9
10

So i deleted it and the:
return $models->newCollection($results['ids'])->map(function ($hit) use ($models) {
            if (isset($models[$hit])) {
                return $models[$hit];
            }
        })->filter()->values();
too, and it's working now, working too if your pagination not in default name "page".
