search url returns 404

Hi!

For some reason nothing happens at the main page while entering something in the search field, although the url changed accordinly (i.e. http://site/ep/search/?q=searchword). it is understandable since direct opening this url returns 404 error:

hp.treatface.ru 127.0.0.1 - - [13/Nov/2015:08:51:53 -0800] "GET /ep/search/?q=test HTTP/1.0" 404 15395 "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/48.0.2562.0 Safari/537.36" 86


at the same time, live search at some pad is working fine:

hp.treatface.ru 127.0.0.1 - - [13/Nov/2015:09:01:13 -0800] "GET /ep/search/autocomplete?q=test&limit=8×tamp=1447434074040 HTTP/1.0" 200 152 "https://hp.treatface.ru/Welcome-to-Hackpad-IsBor2DFgrM" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/48.0.2562.0 Safari/537.36" 44


and url search_live is OK too (although these results are not for direct opening):

hp.treatface.ru 127.0.0.1 - - [13/Nov/2015:09:04:46 -0800] "GET /ep/search/search_live?q=test HTTP/1.0" 200 12385 "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/48.0.2562.0 Safari/537.36" 91


while googling I found exactly the same problem at the hackpad.com itself which was solved somehow even before this repository was created here at github: https://twitter.com/jasonkotenko/status/596078472373608448

this is my environment:

a48@scan-mail:/usr/local/hackpad$ uname -a
Linux scan-mail 3.2.0-4-amd64 #1 SMP Debian 3.2.68-1+deb7u5 x86_64 GNU/Linux

thanks!
