Wrong redirect if url don't match

With the previous code you get too much params and all of these parameters are included to the URL

[osclass] => dc90d557238550502335...
[__utma] => 263180956.1364595168.1401294533.1404999419.14...
[__utmb] => 263180956.8.10.140507...
[__utmc] => 263180..
[__utmz] => 263180956.1401294533.1.1.utm...
[page] => search
[sCity] => ..
[sCategory] => ..
..

Added search prefix previously remouved in constructor
Keep page param.
