How to manage datatable with a table with 100 000 lines

Hi!

I use datatable with a PHP framework (CodeIgniter) which manages a table with records more than 100 000.
The number of lines is too high so I have to paginate lines by loading ajax for example, does this functionnality already present in datatable?

For the moment, I paginate with CodeIgniter pagination but my problem is: I have to use the simple version of datatable

<table class="table table-striped table-bordered">

Now I want to use "Search" but not the listbox "records per page".

How to do that? How to make "Search" work with ajax loaded datas?
