Failed to optimize index: 'default'. Message: background merge hit exception.



I have a standard search on an Azure website and the index got corrupted. Now, I am trying to recreate the index, but it's a large site and it takes ages. Eventually, I got the following errors:

2016-06-07 16:04:31,793 [191] ERROR EPiServer.Search.RequestHandler: Update batch could not be sent to service uri 'http://xxx/indexingservice/indexingservice.svc/update/?accesskey=local'. Message: 'The operation has timed out   at System.Net.HttpWebRequest.GetResponse()

The entire folder is 53.1 MB so far, there are 35K pages in the DB.

Any ideas?

Remove everything in index folder, increase request timeout in IIS and try again?

    <httpRuntime executionTimeout="180" />
