Laravel search not returning any result - laravel

Question

I am trying to create a search where user can search for book title. There is a field in 'books' table called 'title'.
however if I do dd($books); I get:
Collection {#667 ▼
#items: []
}
If I do dd($searchTerms); output seems to be correct
Here's my controller:
function search()
{
$books = Book::all();
return view('layouts/search',['books' => $books]);
}
function details() {
$searchTerms = explode(' ', \Request::input('book'));
$books = Book::where(function($q) use($searchTerms) {
foreach ($searchTerms as $book) {
$q->orWhere('title', '%'.$book.'%');
}
})->get();
dd($books);
return view('layouts/details', compact('books'));
}
Search blade:
#extends('layouts.master')
#section('title')
#section('content')
<h1>Search for books</h1>
<form action="{{url('details')}}" method="POST">
{{ csrf_field() }}
<div>
<input type='text' name='book' placeholder='Enter any character' />
</div>
<input type="submit" name="submitBtn" value="Search">
</form>
#endsection
Details blade:
#extends('layouts.master')
#section('title')
#section('content')
<h1>User Details</h1>
<form>
<p>
<ul>
#foreach ($books as $book)
<a href= "{{url('reader/'.$book->title)}}">
{{$book->title}}</a>
</p>
</form>
#endforeach
</ul>
#endsection

Answer 1

You forgot to tell the eloquent builder that your OR's should have LIKE as the operator:
$q->orWhere('title', 'like', '%'.$book.'%');

Answer 2

Please change the function of details to this
function details(Request $request) {
$searchTerms = $request->book;
$books = Book::where(function($q) use($searchTerms) {
foreach ($searchTerms as $book) {
$q->orWhere('title', '%'.$book.'%');
}
})->get();
dd($books);
return view('layouts/details', compact('books'));
}
