You can achieve this using SharePoint server object model. Example code is below.

SPUserToken userToken;
using(SPSite s = new SPSite(site_url))
{
    using(SPWeb w = s.OpenWeb())
    {
        //UserName comes from the request like keywords
        userToken = web.AllUsers[UserName].UserToken;
    }
} 

using(SPSite s = new SPSite(site_url, userToken))
{
    using(SPWeb w = s.OpenWeb())
    {
        //add your search logic
        //this will use passed in UserName for all SPSite and SPWeb API calls.
    }
}
