there is not way that you get duplicated records

Post::join( 'tags', 'tags.post_id', '=', 'posts.id' )
	->where( 'title', 'LIKE', '%'.$keyword.'%' )
	->orWhere( 'tags.name', $keyword )
	->paginate( 15 );

Hi arcollector,

Your solution won't work for me as the posts/tags relationship is a many to many relationship, and I don't have a post_id field in my tags table, instead of that I have a pivot table where the relation is set.

That's why now I'm trying this:

$posts = Post::where('title','LIKE','%'.$keyword.'%')->orWhereHas('tags', function($query)
{
    $query->where('name', 'LIKE', '%'.$keyword.'%');
})->paginate(15);

But It's still not working, I get a Call to undefined method Illuminate\Database\Query\Builder::orWhereHas() error.

I'll keep trying, thanks for the help!

what about this ???

Post::join( 'posts_and_tags', 'posts_and_tags.post_id', '=', 'posts.id' )
	->join( 'tags', 'tags.id', '=', 'posts_and_tags.tag_id' )
	->where( 'post.title', 'LIKE', '%'.$keyword.'%' )
	->orWhere( 'tags.name', $keyword )
	->paginate( 15 );
