SharePoint 2013 Search re-write host

I am trying to solve a SharePoint 2013 search issue using the F5. We are using ADFS for our authentication so we had to extend the web app to enable NTLM authentication to get the search crawl feature working. We setup out Alternative access mappings and things display ok on the page. The issue we have is when you hover over a document the preview points to the search URL (NTLM) instead of the portal URL (ADFS) and the users are prompted to authenticate.

 

I have tried to setup an empty stream profile and an iRule to replace the hostname but it does not appear to be working. I am also not seeing anything in my logs so I am stumped.

 

iRule: when HTTP_REQUEST { Disable the stream filter for requests STREAM::disable

 

Remove this header to prevent server from compression response HTTP::header remove Accept-Encoding } when HTTP_RESPONSE { if { [HTTP::header "Content-Type"] starts_with "text/" } { STREAM::expression "@spcenter-search.domain@spcenter.domain@" STREAM::enable log local0. "[IP::client_addr]:[TCP::client_port]: Enabled stream filter for spcenter-search.domain -> spcenter.domain" } else { log local0. "Replace rule did not trigger" } }
