On a SharePoint SearchResults page the core results webpart can be refined or filtered using the QueryString paramters 'r=' or 'a=' in the url. I am attempting to use the 'a=' parameter which works great for the fields 'format' and 'author' but I have no been able to get it to filter on Modified Date aka 'write' or on Site Url aka 'sitename'
Example:
//queryString was "r=write%3D%22AQlQYXN0IFllYXIFd3JpdGUAFwFbMjAxMy0wNC0xMFQwMDowMDowMFo7XQ%3D%3D%22"
//removing the urlEncoding %3D%22 you are left with the below value.
r="AQlQYXN0IFllYXIFd3JpdGUAFwFbMjAxMy0wNC0xMFQwMDowMDowMFo7XQ";
/*following decode written by http://stackoverflow.com/users/516910/broc-seib */
decodeBase64 = function(s) {
var e={},i,b=0,c,x,l=0,a,r='',w=String.fromCharCode,L=s.length;
var A="ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/";
for(i=0;i<64;i++){e[A.charAt(i)]=i;}
for(x=0;x<L;x++){
c=e[s.charAt(x)];b=(b<<6)+c;l+=6;
while(l>=8){((a=(b>>>(l-=8))&0xff)||(x<(L-2)))&&(r+=w(a));}
}
return r;
};
s2=decodeBase64(r);
alert(s2);
If you run the code above in your browser you will see the search was 'Past Year | write'. and it returned a few hundred results. How do I get this query to work using the 'a=' paramter ?
