Laravel 5 proper searching and sorting mechanism

I create a Laravel 5 web application and had confronted with some difficulties with sorting and searching.

I have a table with some companies, which I get from a database. This table has several columns: Name, Industry, Country, etc. Table is sortable by clicking on the column header.

The Route for sorting is:

Route::get('/{sort?}/{order?}', 'CompaniesController@index')
->where('sort', 'id|name|country')
->where('order', 'asc|desc')
->name('companies');

Also I use simplePaginate() for paginating output results.

Url for the first page looks like:

http://ift.tt/2hhepVo or http://ift.tt/2gS2Cjr

and with pagination looks like http://ift.tt/2hhgRLN

By this moment everything is working properly. But I also want to use HTML form for search by name, country, etc.

I tried to pass current url to action parameter and got this after submitting a form:

http://ift.tt/2gS0tEB.

I can work with this parameters and use them, but if I go to the second page using pagination I lost query string. I undestood that this way is wrong.

Next I tried to use Search Route:

Route::get('/search',['uses' => 'SearchController@getSearch','as' => 'search']);

with SearchController but I don't know how realise it properly.

I need combined usage of searching, sorting and pagination but I don't know how to include search parameters into the url for proper usage.

Thanx for helping.
