1. I need to find the log with jobid xxx, but the result is different every time after running the following code;
2. I want to use the CreateTime field in reverse order, the following code is not successful;
3. I want to implement fuzzy query, but did not understand the example of elastic docs;

Please help me point out the problem in the code,thanks

Please format your code, logs or configuration files using `</>` icon as explained in [this guide](https://discuss.elastic.co/t/about-the-elasticsearch-category/21) and not the citation button. It will make your post more readable.

Or use markdown style like:

````
```
CODE
```

````

This is the icon to use if you are not using markdown format:

It looks like `.Query(...)` is being called multiple times. This call is assignative and not additive, so the last call assigns and replaces any previous assignments. To combine queries into a compound `bool` query, take a look at the [writing queries](https://www.elastic.co/guide/en/elasticsearch/client/net-api/current/writing-queries.html#combining-queries) and [writing bool queries](https://www.elastic.co/guide/en/elasticsearch/client/net-api/current/bool-queries.html) documentation.
