Sharepoint 2016 search is not working.

Question

Sharepoint 2016 search is not working... Checked the crawl all success.. Reset index then full crawl.... Then while searching the item from share search box... It just saying working on it after long time processing about 10 minutes later get the below error message : "The request channel timed out attempting to send after 00:00:11.3620000 increase the timeout value passed to the call to Request or increase the sendtimeout value on the binding. The time alloted to this operation may have been a portion of longer timeout " So to make the search working what I should do????
