I've gotten some visits to pages that are supposed to be completely hidden from everyone via Yandex and I'd love to find out:what search term led them to itthe referring page on my siteThe problem is that in spite spending over an hour trying to utilize the vars in the URL, I can't get a legitimate search page on Yandex.  Here's the URL in question:http://yandex.ru/clck/jsredir?from=yandex.ru%3Bsearch%3Bweb%3B%3B&text=&etext=1271.RJS9ZfLhVdj6nXam87qy4e0e-DG9BQd_KlyA1gFVBu1uuZOuUSRTgOEasX71Cupm.fe839c38b17c539463c0b2f7d01d86940f4b3320&uuid=&state=_BLhILn4SxNIvvL0W45KSic66uCIg23qh8iRG98qeIXmeppkgUc0YL_nDC5hqtEQ6WayFoZKRZE&data=UlNrNmk5WktYejY4cHFySjRXSWhXUFJiWDhna1NqZnBmd1YzNG43VS13RUpmdUZXdnBLOHdkMFlqUzVDamF1OVBVb2xkMmtvMUxXWUxJM1hSVW5hS2x5R1R6LVpCcGVXZFZZNkprR0JOSUVPc3d0ZnBVOXpDV295ckZDdFpqS3l4WkZSOFF3c0RmVTN2ZkhIYWIwT0JzNVQyWko5ME9vMw&b64e=2&sign=08505d8afebc7cb1b4568d3e92c11ecb&keyno=0&cst=AiuY0DBWFJ7IXge4WdYJQXbYQp9t5VF6sf_IfF4r6pdt0ojCe4cFQNegojWnJn8UToJJyLyR96RrC_bl9mqJxfCjbo3nl3EPqUjNd2ADc0Zxar8tKC1hQd4R3WTMI1AD3dVkg_IhwheNgkWXjuLnig&ref=orjY4mGPRjk5boDnW0uvlrrd71vZw9kp5uQozpMtKCXdCnh-_wii4V8gT36dWFhYdLgT8HVc5IPL1yluhUPYHlzmn9nr8Aaa3y8eC13fJRd5RgTTAPeGmg&l10n=ru&cts=1481853806438&mc=4.32492874929I took the code after the redir URL and tried adding the var and value etext on to the Yandex search URL but nothing has worked so far.I've already downloaded the entire site via wget while using both a browser and Yandex search UA (it's how my site distinguishes bots to hide logins and human-specific content).  Doing a search through all the downloaded content, I was unable to find any instance of the URLs in question. The sitemap has no mention of the URLs in question.
Is there any way to extract referrer and search term from a Yandex redirect URL?
