How to search case insensitive in Eloquent model

I suggest Upper function in this case

Model::whereRaw("UPPER('{$column}') LIKE '%'". strtoupper($value)."'%'"); 

like this

Actually, you don't need to use UPPER, just use ilike as the comparator and it will do a case-insensitive comparison.

Model::where('column', 'ilike', '%' . $value . '%')

You do need the % signs to signify the substring you're searching for.

Didn't see this solution. so I'm posting this here.

DB::table('products')
   ->select('productid')                
   ->where(DB::raw('lower(product)'), 'like', '%' . strtolower($searchword) . '%')
   ->get();
