    Dump out your $request and have a look at it, like :

    dd($request);

    You probably want to access the values like :

    $request->input('value');

    instead of trying to access it as an array.

    you can make the following changes , so that it works dynamically based on the given

    public function search(Request $request)
    {
        $request = $request->all();

        $models = Course::query()
            ->when(array_key_exists('value', $request), function ($query) use ($request) {
                $query->where('title', 'like', '%' . $request['value'] . '%');
            })
            ->where(['deleted' => '0'])
            ->get();
        return response()->json($models);
    }

    here we have when statement to check whether this key exist or not , in case of non existence it won’t execute with that particular key else it works as desired.

    when(array_key_exists('value', $request), function ($query) use ($request) {
            $query->where('title', 'like', '%' . $request['value'] . '%');
        })

    you can also modify when statement, or if you want more conditional statement than you can also append those inside the above-mentioned statement.

    del one line and use

    &request->value;

    like that

    public function search(Request $request) {
$models = Course::query()
        ->where('title', 'like', '%' . $request->value . '%')
        ->where(['deleted' => '0'])
        ->get();
return response()->json($models);
}
