I am querying for results of [/search/advanced](https://api.stackexchange.com/docs/advanced-search). The request I am sending is  

    https://api.stackexchange.com/2.2/search/advanced?key=`key`&access_token=`access_token`&site=stackoverflow.com&page=1&pagesize=20&order=desc&sort=relevance&q=signalr&filter=!tRhd)yG5RfdF0fv8E-NwvlZNrfzIwPf  
The question as marked in this snapshot[![enter image description here][1]][1]  is not present in the json result.  

Also, question titled `SignalR - StartUp` has `is_answered = true` even when there is no accepted answer. Another question `signalR undefined` has `is_answered = false` which has same conditions, i.e., no accepted answer. Here the first case is giving wrong results.   

Kindly give `access_token` and `key` in the above link.
