Specifying Title URL in List View Webpart

I want to set the Title Url something like

/sites/somesite/SitePages/MySearchPage#Default={\"o\":[{\"d\":1,\"p\":\"AverageRating\"}]}

where 'AverageRating' is one of my columns using which I am trying to run my query to the search page. While setting the above Url in web part advanced settings it prompts as :: the Url is invalid.

Also, I have tried setting 'listUrlDir' property of context in my JavaScript but that also didn't work out. 

Somebody guide me with the proper way.
