Query remembers it state.

[Siebov]

$query = $this->proposal->where('status', 'approved')
            ->with(['evaluations', 'user', 'contributions'])
            ->with(['reviews' => function ($q) {
                $q->where('status','approved')->orderBy('created_at', 'desc');
            }]);

...

dd($query->toSql()); // "select * from "proposals" where "status" = ?"

$proposalsFoundByTile = $query->where('title','like',"%$request->search%")->get();

dd($query->toSql()); // "select  from "proposals" where "status" = ? and "title" like ?"

...

Why $query value changed? How can I "clear" this changes to initial value?
