Search With Filters from Other Tables - laravel

Question

I try to build a search query with different params but some of the filters columns comes from other tables who are in relation with another table , i don't know how to achieve that
For exemple the column "compet_id" comes from my table Rencontre.
In my table RencontreOfficiel i have rencontre_id to make the relation with "Rencontre"
I'm not sure if my clear it's a little bit difficult to explain ; hope someone could see and help .
here my controller :
$query = RencontreOfficiel::query();
$filters = [
'compet_id' => 'compet_id',
'structure_id' => 'structure_id',
'catg_compet_id' => 'dt_rencontre',
'fonction_id' => 'dt_rencontre',
'bareme_id' => 'bareme_id',
'dt_min_rencontre' => 'dt_rencontre',
'dt_max_rencontre' => 'dt_rencontre',
];
$dt_min = $request->input('dt_rencontre_min');
$dt_max = $request->input('dt_rencontre_max');
foreach ($filters as $key => $column) {
$query->when($request->{$key}, function ($query, $value) use ($column , $dt_min , $dt_max) {
$query->where($column, $value)->orWhereBetween('dt_rencontre' , [$dt_min , $dt_max]);
});
}

You can use whereHas and with keyword in Eloquent search.
for example you have Blog method that connected to User model. every Blog send by user . If you want to have search in User according to his blogs you can use this :
$user = User::where(function($query){
$query->where('age','>=',18);
})->whereHas('blogs', function ($query){
$query->where('text', 'LIKE', '%game%');
});
In this code blogs in whereHas method is name of Eloquent method in User model.
Result : this code return users older than 18 years that have blogs with title like game.
