Page Comparison

Description:

When navigating on When "using pagination control (e.g. changing pages between 2nd and 3rd and back) on search results pages URL transforms into very big string where sorting parameters are the "sort_by" URL-parameter value is duplicating many times.

Steps to reproduce:

Install clean In-Portal copy with Advanced theme from SVN-repository
Install In-newz module;
Make sure that Advanced theme is primary on your In-Portal installation;
Go to admin part and create 11 articles (in my case there were articles with title "Lorem ipsum");
Go to front-end part and in left "Search" side box type request which definitely find your all 11 articles ("Lorem ipsum" in my case);
On "Articles Search Results" go to bottom of the page and click "More..." link;
On this page click on link of second page of results. Query part in address bar of browser will change to something like this: " http://localhost/in-news/articles/search_results.html?sort_by=Relevance,desc|CreatedOn,desc&page=2";
Goto bottom of this page and click on link of first page of results. It transforms query part in address bar to something like that: " http://localhost/in-news/articles/search_results.html?sort_by=Relevance,desc|CreatedOn,desc|CreatedOn,desc";
Click again on link of second page. Our desired part of request will be like that: "http://localhost/in-news/articles/search_results.html?sort_by=Relevance,desc|CreatedOn,desc|CreatedOn,desc|CreatedOn,desc&page=2".
