Improved messages search API endpoint

There’s an improved way of fetching a large set of log messages from the API. Previously (you can still do that) you’d have to use pagination to get more than 100 messages:

https://api.elmah.io/v3/messages/LOG_ID?pageSize=100&pageIndex=2

The data is stored in Elasticsearch which doesn’t allow pagination in more than 10,000 documents. With the improved API, all search requests return a new searchAfter property:

{
  "messages": [
    // ...
  ],
  "searchAfter": "1694180633270",
  "total": 42
}

In subsequent requests you can provide the API with the value of the searchAfter property to pick up where you left off:

https://api.elmah.io/v3/messages/LOG_ID?pageSize=100&searchAfter=1694180633270

The change is available on the API and in the Elmah.Io.Client 5.1 prerelease NuGet package.
