I have the following request JSON for ES query. It gives me following error:

> 
> [ImageURL] query malformed, no start\_object after query name
> 
> 
> 

when i add `must_not` under `bool`. if i remove `must_not`, it works fine. I want to get records where "ImageURL" is not null

Where i am doing wrong? Please help
