Search system improve

When you view a lot of search results, after a while new results stop loading after scrolling down. This is not the only problem - the page itself becomes too long. 

A way to solve the proplem is a page system, where you can scroll continuously. It can look like now, but "old" results will be removed from page. 
- Only three blocks (pages) remain active - the previous, current and next. This will allow you to smoothly delete results from which you have already moved away. 
- Also it would be nice to add page navigation (a small block with a number on the left or right). 
- Such page system will allow developers to add the page number to the address bar so that the user remains in the same place even after the page is reloaded.
