Laravel migration - can't add unsigned and index

When creating migrations, can I add "unsigned" and "index" in this way?

        $table->integer('user_id')->unsiqned()->index();

or only "unsigned", like this:

$table->integer('recipe_id')->unsiqned();

When I do this on my table "user_recipes", only the primary key becomes unsigned. User_id doesn't get "unsigned" nor "index":

public function up()
{
    Schema::create('user_recipes', function (Blueprint $table) {
        $table->increments('recipe_id')->unsiqned();
        $table->integer('user_id')->unsiqned()->index();
        $table->text('recipe_content');
        $table->timestamps();
        $table->boolean('hasbeenconverted', 50);

        $table->foreign('user_id')->references('id')->on('users');
    });
}

But the above column "recipe_content" becomes "unique" and indexed - how come??

I do the same thing in the table "user_custom_categories", and in this case the user_id became unsigned but no index was added. The auto increment primary key went unsigned also.

public function up()
{
    Schema::create('user_custom_categories', function (Blueprint $table) {
        $table->increments('cat_id')->unsiqned();
        $table->integer('user_id')->unsigned()->index();
        $table->string('custom_category', 50);

       $table->foreign('user_id')->references('id')->on('users');
    });
}

And on a third table "recipe_category_relations", only the primary "id"-column became unsigned with this code:

public function up()
{
    Schema::create('recipe_category_relations', function (Blueprint $table) {
            $table->increments('id')->unsiqned();
            $table->integer('recipe_id')->unsiqned();
            $table->integer('category_id')->unsiqned();
            $table->timestamps();

           // $table->foreign('recipe_id')->references('recipe_id')->on('user_recipes');
           // $table->foreign('category_id')->references('cat_id')->on('user_custom_categories');

    });
}
