**with query conditions, I filtered out only one doc, part of the doc \_source is :**

> ```
> "_source": {
> "event": [
> {
> "time": 1520252057459,
> "duration": 1876,

> "cdn_ip": ""

> {

> "duration": 0,

**query body is as follow , I got the avg value of speed, but the value is obvious wrong, how can I exclude out those dirty events such as the _"firstBufferingEnd"_**?

Read [this](https://discuss.elastic.co/t/about-the-elasticsearch-category/21) and specifically the "Also be patient" part.

It's fine to answer on your own thread after 2 or 3 days (not including weekends) if you don't have an answer.
