Global search doesn't work if sorting is disabled

[nesl247]

Currently you are checking to see if a column is orderable in order to perform a global search. You should instead be checking to see if it is searchable.

On https://github.com/bllim/laravel4-datatables-package/blob/master/src/Bllim/Datatables/Datatables.php#L517

Change: if (isset($columns_copy[$i]) && $this->input['columns'][$i]['orderable'] == "true")

To: if (isset($columns_copy[$i]) && $this->input['columns'][$i]['searchable'] == "true")

This fix worked for me.

Sorry for late reply, I was very busy this summer... You are right, I didn't notice that. This will be changed.
