Searching value in already cache data from database in laravel - laravel

Question

I am learning to make caching and as I know
if(cache::has('cacheKey')) {
cache::get('cacheKey')
} else {
$data=cache::remember('cacheKey',time,function() {
return db::table('user')->get();});
return $data;
}
now question is when I am trying to search a specific data on key and then on result paginate that data for this I did use Cache::remember but how can make this fast when I am using all the time cache::remember function when I am trying to search in cache key, here is code
$page = $req->has('page') ? $req->query('page') : 1;
$keyword = $req->keyword;
if(cache::has('FileData')) {
if(!empty($keyword)) {
$file = cache::remember('FileData'.'search='.$keyword.'page='.$page,1440,function() use ($keyword) {
return File::with('callcase','lettercase','update_table','fileimages')
->where('id','Like','%'.$keyword.'%')
->orWhere('file_name','Like','%'.$keyword.'%')
->orWhere('recieved_by','Like','%'.$keyword.'%')
->orWhere('processed_by','Like','%'.$keyword.'%')
->orWhere('address','Like','%'.$keyword.'%')
->orWhere('contact_no','Like','%'.$keyword.'%')
->orWhere('show_status','Like','%'.$keyword.'%')
->orWhere('Reopen','Like','%'.$keyword.'%')
->orderBy('id','desc')
->paginate(25)
->setpath('');
});
$file->appends(['keyword'=>$keyword]);
if(count($file)>0) {
return view('home')->with('files',$file) ;
} else {
$error = "File does not found , Search another using keyword ";
return view('home')->with('filemsg',$error);
}
} else {
$file = cache::remember('FileData'.'page='.$page,1440,function () {
return File::with('callcase','lettercase','update_table','fileimages')
->orderBy('id','desc')
->paginate(25);});
return view('home')->with('files',$file) ;
}
} else {
$file = cache::remember('FileData',1440,function(){
return File::with('callcase','lettercase','update_table','fileimages')
->orderBy('id','desc')
->paginate(25);
});
return view('home')->with('files',$file);
}
My code is working fine and returning data as i wanted but i am confused on this when every time i am making remember data then how can i make that faster it would faster when i will retrieve data from already cache key and search in them and paginate them , How can i do this and help me if somehow i am doing wrong.
